I've gone back through this thread (if I've missed, or misrepresented, 
anybody who's expressed an opinion I apologize now).

followed by Maxim's approach and lastly the existing git-svn mirror."

FWIW, I now support using reposurgeon for the final conversion.

And, of course, I'm taking Joseph's opinion as read :-)

So I don't see any clear dissent and most folks just want to get this

The main differences are

a) more revisions added due to commits upstream
b) release tags from SVN era now on the main release branch rather than 
in sidings
c) more author fixups from Joseph's cross validation against your 
repository and reposurgeon's own reports of suspect attributions
