Regressions are avoided by a larger variety of people doing testing.
Not enough people currently give feedback on -proposed.  Adding tiers
to -proposed would reduce the number of people testing each tier.  I think
this would result in a net loss.

I would propose that increasing the number of people giving feedback on
-proposed would be the better solution.  I don't have a specific plan
for how to implement that, but it seems that a tighter communication loop
between people using -proposed, LP, and a log of what they've installed
and when (some kind of additional bug-filing wizard) could reduce the
technical knowledge needed to provide useful feedback on proposed.
And let them revert/blacklist an update easily.
