Let me just disagree with you ;)

There's a very reasonable assumption that things will fail on a new
architecture, so it makes more sense to whitelist things when they have
been tested, patched and beaten into submission.
Blacklisting things is not good when you want everything to build,
because it's hard to get enough test coverage (build everything on HPPA?
You funny person ...) and to keep the blacklist updated for new versions
(Who would have guessed that Java/Icedtea still doesn't build on SPARC?)

(On a sidenote, if you are in a I-Don't-Care mode you can just tell
portage to accept anything - or that anything that works on x86 should
be ok too. But that's Not A Good Idea :) )

And luckily your "Gentoo needs Gentoo" claim has been undermined over
the years, first by Gentoo Prefix (which even works on win32 and other
mad platforms) and lately by RAP ("RAP ain't Prefix") which started as
an experiment on Android (

Have fun,
