Does anyone honestly believe that 8.3 will not lead to accelerated prefix lengthening?

When you take the central registry out of the reclaim/reissue process you virtually eliminate
all likelihood of any form of returned-block coalescence which was a relatively low probability
even with everything going through a centralized process.

When you combine this with the fact that the intent of the single-aggregate language has
been superseded by legal interpretation (legitimately, the phrase was poorly written) and
there is now pressure to simply eliminate the language instead of restoring it's intent, I
believe that things are only going to get worse.
