Yes. That's indeed the way I chose to follow for Mojo because after
twiddling a bit with filter-branch, I was quite sure it would be slower but
a lot easier to just git svn clone mojo by mojo (hence the csv file,
specifying the tags&branches for each mojo [1]). I also

And I can certainly relate about the sluggishness. It took about 2 or 3
minutes even for very small mojos, and I had the whole SVN imported locally.

In that current case, I've always seen svn repositories available at GitHub
as automated facilities somehow only to be able to file PR against the svn
trunk, but not as real Git clone that could be used for a migration.

Yep. But even if I'm not even sure every required commits are here, I'm not
sure that would be interesting to do it apart from learning a bit more
black magic :).
