I assume we would do this so the urgent security updates don't get stuck
in -proposed for a longer than desired timeframe? The problem with doing
this is it's going to be really hard for us to not collide with version
numbers, and making sure that subsequent uploads still contain the
security fix, etc. While it may be worthwhile for a world-burning issue,
I don't see this as being reasonable for the majority of security
updates for which we'll simply upload them as usual.

Pardon my ignorance, but what does a "P-U-P value over 100" mean?
