For x86-64 and ia64 this makes sense. There are a good
number of non-free binaries out there -- though I must
admit that Debian traditionally gives non-free binaries
the cold shoulder.
Those of us running ppc have long gotten used to doing
without any of those non-free binaries. There isn't any
compatibility benefit to supporting 32-bit stuff. It's
only a matter of performance: do you want 1 glibc in RAM,
or 2 of them in RAM?

That may be, but they did manage to compile a number
of packages as 64-bit. This isn't another case of
slapping a 64-bit kernel and libc on a 32-bit install
and calling it good.
If you really want a 32-bit userspace, remember
that you can simply run a 32-bit distribution.

Well, that looks like the thing to run on a Mac G5.
Gentoo is planning ahead and keeping things simple.
Alternately, run a pure 32-bit system. Why not?
Let's not complicate things for no good reason.
