AFAIK 10.5 was the last macos version that ran on PowerPC, so "≥10.6"
already implies that macos-on-PowerPC is not supported.

Officially, yes, but some people apparently manage to run 10.6 on
powerPC. I don't know if we really need to specify that, though, given
that it's almost certainly a tiny subset of a tiny subset of people
running macOS, and they can't reasonably be expecting official support
for their project.

Interesting.  Makes me wonder, tho: why would Emacs not work on such
a system?  I understand that with the old unexec there was a good chance
that it wouldn't work without explicit work on our part, but the "p" of
"pdump" should avoid those problems ;-)

Yeah, I was thinking that. I can't think of any reason it wouldn't
work with the exception of some NS specific image format code (PBM or
something?) where I think we recently switched from big-endian to
little-endian. But given it took us years to notice that was broken, I
can't see it causing any problems. :)
