Me too, and I don't think we shoudl try to provide a seamless transition
for every possible use case.

Those people would either stop using SVN externals for Boost, and simply
check a copy of Boost into their source tree, or maintain their own SVN
mirror of the boost releases (at least the ones they're interested in)
and then point their externals to that mirror.

I think that's a bad idea, because it would leave us responsible for
maintaining a correspondence between said git repo and our other reality
that meets peoples' expectations. Furthermore, I don't see how
providing a Git repo is going to be much help to people that are using
Boost is making this transition. It *will* cause some disruption. It
will also make things easier for some people. IMO we should not burden
this move, which is supposed to make it easier and more efficient
overall for Boost to operate, with any unnecessary obligations.
