Just demote it to tier-3 so we don't even try to provide packages,
but I'd like to see ppc{32,64} kept alive for two reasons, other
than being a sentimental favorite for a number of FreeBSD folks. :-)
PPC takes a kind of special place among other no longer mainstream
arches due to mass production of good quality Apple hardware which
is scattered around the world and is still useful as a backup boxen,
NAS, etc. despite no longer competitive performance while you can
still plug and rotate modern disks and network cards.

Which I see as a plus: weird hardware helps to hunt obscure bugs.

This is my second reason to keep it around: different endianness,
char signness, 32-bitness force one to write well-typed, correct,
sound code.

I use both ppc32 (Mac mini G4, actively) and ppc64 (G5, currently
offline due to known military conflict).
