Oh, but all the other points still apply:

OS X 10.4 itself is unsupported for 5+ years.
No Emacs developer has it to test on.
All the bug reports about it come from one person (who seems to be doing
an "explore the compilation parameter space" thing rather than actually
wanting to use it).
All the bug reports are about PPC;
  http://debbugs.gnu.org/cgi/pkgreport.cgi?include=subject%3A10.4;package=emacs
 (whether this means it is working fine on non-ppc, I have no data for! :) )

So personally I see no value to pretending it is still supported, and
think it might as well be explicitly dropped.

Should be easy?
