The problem that I've got with relegating PPC to a secondary arch is
exactly that there are few other candidates for arches that will command
enough interest to force maintainers to pay attention.  And that will
mean that Fedora becomes an x86 monoculture over time --- apps won't
work on anything else, and their maintainers won't take any interest in
fixing them, and that provides reason for other maintainers to stop
worrying about portability of their apps, and it's a vicious circle.

Right now, people are at least compelled to pay some attention to basic
issues like endianness.  If the only primary arches are little-endian
then hardware independence is going to disappear.
