I think I was being misunderstood. I am indeed a great fan and didn't
want to rant against git. I just came to accept that as long as
there's sentiment there's no transition possible.

Not at all doable. As I said, one may be able to hack this or make it
work but it's not a defined or supported way of working with it. And
using such a system in a way that defies its intended way of being
used is pointless and will only support those who claim git itself is
not a good thing.
Sure, you may be able to cut your fingernails with a chainsaw but life
is just better and a little safer if you don't do it and it adds to
the chainsaw's reputation to a way that it doesn't deserve.

git-svn specifically mentions that usage as being not supported. Two
way svn syncs with changes on both ends are a no-go. I have tried that
in the past and it didn't work out. Which means: Challenge not
accepted! ;-)
I have substantial experience with transistions like that in several
projects in my past and I have the strong opinion that either you do
it right or you don't do it at all. Any compromise along the git-svn
lines except an initial export is bogus.

As I said, it would have been nice, but existing sentiment forbids
chasing that any further. The boost community should just accept this
as consens and be done with it.
