These concerns would indicate holding off on rebuilding until the gcc4
changes can finish landing.

These would indicate rebuilding now so there's still time to fix things.

I'd propose removing from the FC5 package repository any package built
before a certain date (which takes into account your first set of
requirements above).  That way there are no stale packages in the Extras
repository for FC5.  Maintainers who want to be prepared for possible
issues with their builds should begin submitting their packages now
(even if they'll have to be submitted later as well.)

I would like to see orphaned packages require a new maintainer in order
to be pushed to the FC5 repository.  Ville's posted blender bug shows
that pushing packages into current repositories without active
maintainers can lead to serious issues.

If we simply don't ship anything built before some date and we require
someone to request the rebuilds then we'll know someone was working on
the package in the recent past.  If we do an automated rebuild we're
helping to foster unmaintained packages.

If we think the build system is going to be swamped we could think about
assembling a second submission infrastructure to handle release time
(actually, though, it may make more sense to use the current
infrastructure for this and create a new one for higher priority,
security releases.  This would have benefits throughout the
distribution's life, not just at release time.)

Do we need an "Extras Release Manager"?
