Well, real needs would be like: axial resistor: 0.4" vs 0.5" vs 0.6"
spacing, TO-220 standing up or laying down, or the 0603[LMN]
differences.  The last is probably project-wide, but the others depend
on the specific layout of that part.

Ah, but if we're clever with the names, PCB would know how to group
alternative footprints that are for the "same" package.

Well, yeah, but it's a goal, not the "next step".  I often want to
swap gate pins (or memory addr/data pins) in pcb to make the layout
work.  Putting that functionality in gschem is useless; gschem doesn't
know what the layout looks like.

That too.

All the more reason to have PCB give you a way to select among them
for "that package type".
