I would urge us to make changes to the master avatar stuff with notice and encouragement of folks to write FAQ, wiki entries, mini-apnotes and anything else that will help cut down on confusion of those who have significant effort invested into builds on existing regions.

Master avatar should not even exist in the way it still does today, that is legacy. The very same thing can be done in another way (code-wise). So the existing master avatar stuff can be removed,if that is the only blocker, i'll think up some new semantics for that and implement it.
