That's exactly the kind of thing I'm talking about. The exact mechanics
could work in a number of ways:
an across-the-board minimum allocation size, a maximum deaggregation
factor (such as 4 bits longer than the current allocation size, as in
your /16 to /20 example), or more likely some combination of things like
that. But IMO the most important factor is that we preserve as much
top-level aggregation as possible, to preserve the ability to filter
deaggregates if necessary without losing reachability.

Based on the discussions at ABQ, I think that discussion has now started
in earnest, and that we should continue it here and see if we can get
consensus around a possible policy proposal.
