So would I. So far I expect a little cleanup needed after the migration 
anyway, so any other related work could be done then as well. As long as the 
effective migration is done with enough time before to the next tagging, there 
should be no big problem. Should be effectively less work to do in the end.

And for old, unmaintained branches the split-up in several repos results in a 
broken build-setup anyway, as can be seen with the previous migrations, so 
that by-effect seems officially accepted ;)
