I'm probably missing something obvious, but even reading the original
bug report leaves me confused as to how a lack of stable mm-sources
ebuilds is breaking systems.  Once mm-sources is installed anything
that needs a kernel tree should build just fine.  (I don't think
we have anything in the tree that specifically requires mm-sources,
do we?)  If the problem is that somebody wants to install mm-sources but
can't because all ebuilds are arch-masked, then that's what
/etc/portage/package.keywords is for.

I don't know what the official thinking on this is, but off-the-cuff I
would tend to think that _all_ mm-sources ebuilds should really be arch
masked, since mm-sources is both bleeding-edge (by definition) and a
fast-moving target, so one expects that mm-sources ebuilds aren't likely
to be in the tree long enough to really become "stable".  Only
arch-masking release candidates seems a tad silly.  I suppose that one
might argue that they should be package masked, but since new kernels
aren't built and used automatically, I would prefer to just leave it up
to users to decide whether or not to build and use any given kernel.

I agree that Greg's bug report was a tad terse, but I rather doubt that
your allegation of his motivation is correct.  

Now, as to the actual issue at hand, the common unwritten policy is that
packages generally have one (or at most a few) stable ebuild(s) and zero
or more arch-masked ebuilds.  Ideally, every mature package should have
a stable ebuild (preferably stable on every arch), but....  That said,
it's not a written policy because some packages have different needs,
and it's mostly up to the package maintainer to make those decisions.

Incidentally, we often have people suggest that ebuilds should never be
removed from the tree.  Then these sorts of problems would never arise.
If you've done a new install recently, though, you already know how long
it takes to download the initial tree, and that's with fairly active
pruning.  That's a problem that we don't have a really good solution
just yet, so for the moment we try to keep the tree pruned and we let
users who need old versions extract them from viewcvs.

Best,
