Yes.  I've commented on the thread.

I doubt that.  i686 will most like go to a secondary arch status like
ppc64 is today.  ppc32 has been demoted even further down than
secondary arch, as the secondary arch team that was working on it no
longer wishes to do so.

In essence, ppc32 is now analogous to sparc and ia64 in Fedora.

Actually, it's a very very big thing.  Those wishing to keep it alive
now need to come up with their own build hardware and build enviroment
setup.  This is by far the largest hurdle, and if it isn't done
quickly the ppc32 secondary-secondary (thirdary?) arch will quickly
fall behind and into disrepair.

As someone that actually was crazy enough to do this kind of thing
when ppc/ppc64 was originally dropped, I would highly recommend you
get on it immediately.

Which is why I sent it as a patch instead of simply committed it.
Discussion is requested.  At a minimum though, I really would like to
drop the -smp flavor because it was of very limited use even when ppc
was a primary arch and it adds the most complication to the spec.
