In short, software defined can mean whatever you want it to mean. More correctly, they are non-user reconfigurable software defined radios that are incompatible with PowerSDR. A better statement is that PowerSDR's general design is compatible only with Flex-Radio style hardware architectures, and it only includes hardware drivers for the SDR1000, Flex5000, and SoftRock.

Just like hams, we also like to have all the functioning and internals laid out for us so we can tinker and modify, or just understand what it will do in an off-nominal situation(i.e. no magic proprietary modem ASIC). We tend to be concerned about efficiency because space qualified processors are a couple generations, if not more, behind... we're just starting to use a 100MHz SPARC V8 as a bold advance from a 25 MHz SPARC V7, no multi GHz Intel CoreDuos or AMD QuadCores flying to Mars or Jupiter any time soon.

A lot of ham radios that do fit the typical definition of 'SDR' are failing miserably when it comes to my stated position above. And I'm finding it increasingly difficult to even consider radios that have large HW constraints to their SW define-ability. You're not alone. There are some practical problems.. sometimes the hardware constraints come from some performance reason (however, semiconductors are getting better every day..20 years ago, a 10 MHz A/D with 10 bits was really awesome. Now you can get 14 bits at 1GHz). We're probably a ways from the HF nirvana of the 30 bit converter at 125 MSPS where you hook an antenna to the A/D, and you're done. Likewise, high power amplifiers have their idiosyncracies that are not all entirely compensatable in software. Probably a bigger issue is the legal one. Hams are a small volume market compared to radios in general. The radio in general market has regulatory restrictions on just how flexible that radio can be to prevent users from just loading up a version of the software that radiates out of band or receives where you're not supposed to be listening. So, a manufacturer that is trying to leverage commercial radio designs for the ham market (since the ham market can't support huge RD budgets) winds up building radios that inherently are not-user-modifiable. And, there's the Part 15 rules, too. (having the software in mask rom or OneTimeProgrammable PROM makes it easier to pass FCC muster for ham rigs.) It's instructive to look at all the hoops that Icom had to jump through to get the IC-7000 approved.. their filings are on the FCC website. Think of the complexities in modern autotuning HF amplifier designs.. they have little microcontrollers that sense the RF frequency and turn the amp off if you're out of band, and you can bet that microcontroller isn't something you can easily modify. We're faced with a real challenge.. It's easy to build a software radio based on a PC and a simple LO/QSE/QSD like the Flex or SoftRock that has instantaneous bandwidth of over 100 kHz. Even if you put (closed non-modifiable) firmware into the DDS control that restricts the DDS frequency to the ham bands, you could receive and transmit 50 kHz outside the bands. Historically, this hasn't been a big problem (transmitting) because the radios were inherently narrow band. Even if you were set on LSB, and tuned the VFO to 7. MHz, the most you could do is transmit something at 6.995 or so. So the regulators have guard bands between the allocations and spurious emissions requirements to accommodate this. The last thing we want the regulators to do is mandate hardware frequency limits (e.g. filters). Nor do we want them mandating nonmodifiable firmware/software to achieve the same thing.

You could use PowerSDR's user interface to send commands to and get status back from the 7000. You could feed the audio to and from PowerSDR, and use PowerSDR's very powerful filtering, AGC, recording, etc. features. Granted, you don't get some of the performance aspects of doing the modulation and demodulation in the PC (like multiple receivers in the passband) But that's kind of the cool thing about software radios in general.. with half way decent interface abstractions, the RF hardware becomes just a peripheral interface, controlled as you like it. It's sort of like the popularity of programs such as HRD.. they essentially abstract the radio's function and present a common user interface for all radios. One could argue that maybe the direction to head for PowerSDR type products is to let UI specialists (HRD) take on that aspect of radio control, making the software like PowerSDR more of a radio abstraction layer that controls the RF hardware and the DSP processing. CAT on steroids, if you will. But, as you say, for today, PowerSDR doesn't support the IC7000 and TS2000.
