As far as I'm concerned, this community can make that decision.

I had hoped to actually use the svnsync repository so we could all benefit
from the pretense that we'd been using merge tracking all along. (And also,
not knowing if in our history there are invalid proto-forms of the
svn:mergeinfo property that might cause segfaults or worse when we hit 'em.)
  Several other folks have expressed interest in the same.

But if folks want to do a tip-of-the-tree only migration of svnmerge
properties to svn:mergeinfo (using the svnmerge-migrate-history.py script)
and just suffer from whatever badness might exist due to their possibly
being older, incompatible forms of the svn:mergeinfo property in our
repository history (due to us using unrelease code against our own
repository), so be it.
