What I'd heard from multiple sources was that they only wanted the 8085 to replace the 8080, so it was supposed to be "better" in terms of being a lower-cost 8080 replacement, needing fewer support chips (except an address latch, but that's cheaper than an 8228/8238), but they didn't want it to have a better instruction set that might put it into sockets that might otherwise get filled with an 8086/8088.
