I'm for mass rebuilds at freeze time, I also tagged that on this
thread, and I'm glad I see this parallel issue: Just to give an
example of what happens w/o mass rebuilds (and it had to be one of my
packages ... ):

A rebuild of apt for a minor buglet lead to different names of apt's
library because apt wants to embed glibc's version in its libs, so the
update broke synaptic and anything else that would be dependent on
apt (I'm glad this happens now in the updates-testing repo!).

The decision of apt to code in glibc' version may be questionable, but
it is there and I had never bumbed over it for the last 3-4 years, so
it was also forgotten by me. But I don't want to have to think about
which package may break if there is no mass-rebuild and a single
rebuild later will find a completely changed environment.

Just to add some more random rant on the decision to not mass-rebuild:
It was said that the glibc didn't change from FC6 to F7, still stuuf
like fakeroot (or fakechroot, I forget) break due to changes in
chownat and friends (just try installing the FC6 version on F7).

So even though developers/packagers etc. were guaranteeing that the
build chain changes from FC6 to F7 did not require a package rebuild
I'm experiencing quite the contrary.

In a nutshell: We need a mass-rebuild at the end of the development
cycle, immediately before the freezing!
