Why do you believe that? It seems to me much, much easier to untangle
undesired dependencies after the repositories are split.

Git submodules are not part of the long-term plan, at least, not for
most developers. The idea is that the ryppl tool prepares a workspace
for you that includes all of the dependencies. The code surely doesn't
work right now, but that's what we implemented in, and I expect to ressurrect that work
after the Boost SVN->Git transition is complete.
