Yes, it seems obvious to me to use git for maintaining
the feature branches containing my ports, and as you point out
it makes it easy to maintain multiple feature branches
containing different contents.  Keeping the names disjoint will
prevent messy conflicts.  I am by no means a git expert and
I already do this all the time for other projects.
