It seems like there is room to add a footprint selector utility that
would interface between gschem/gattrib and PCB without impacting
non-PCB users in any way. In fact if PCB had an HID where it just
starts up as a footprint browser and nothing else, you could use PCB
itself to assign footprints to symbols from within gschem or gattrib.
An option in the gschem config file could allow users to define a
command line to start PCB in that mode, and PCB would output the
selected footprint attribute value before exiting.
Users of other workflows might be able to use a similar type of browser
utility to work with other types of libraries -- gnucap models?
verilog models? I don't know if that would be useful or not...
Anyway, the point is that this type of feature can be added and could
be be completely invisible to other workflows, unless they want to use
it.

I think that (1) our tools are mature enough that users should expect
*some* sort of seamless integration and co-operation between them, and
(2) we're mature enough to not have to insult our users when our
software acts in an unexpected way.

Irrelevent. Having clean interfaces doesn't preclude using those
interfaces in a seamless manner, giving the impression of integration.

Hence the Terminology chaper in the Getting Started guide, which
defines what PCB means by footprint:
``A footprint is the pattern on a circuit board to which your parts
are attached. This includes all copper, silk, solder mask, and
paste information. In other EDA programs, this may be referred to
as a "land pattern". "Footprint" sometimes is used to refer to a
footprint file. "Footprint" refers to the pattern; "element" refers
to the instance. For example, your layout might have four elements
that use one footprint.''
If you're talking about PCB, please stick with PCB's meanings of the
terms.

And some programs aren't EDA programs, but that doesn't help with his
problem.

Please stop trying to push your personal flow onto others :-)
Despite you pushing your personal way of doing things (very vocally, I
might add), a clear majority (not "some") of the geda users DO want a
simple schematic -> pcb flow that's well integrated and easy to use.
Your personal choice is *not it*. Yes, we want to make your flow
*possible*, but we really need to make the "dumbed-down" environment
easy to use and streamlined, because that's what most people want.

Flexibility and ease of use should not preclude each other.
