Now you're talking! :)

If you are ready to monitor the issue closely, I don't see any problem
in switching the default now in unstable, see how it goes, and then
decide later on if revert back to the current default in Squeeze
time. Ideally, you should probably communicate a on the matter when/if
it arrives in testing to raise the awareness for testing users (and
probably we should work on the doc, as reported by Vincent). AFAICT the
change of the default change is relatively self-contained and will only
help in showing other problems which has been difficult to spot thus
far. [ I'm Cc-ing the release team, in case they see extra problems that
I don't in doing that change in the interim. ]
