But for that I think "git bundle" should learn new subcommand:
"git bundle update", which would use refs existing in given
bundle as prerequisites, and either update bundle (create anew
or just concatenate next pack) or create incremental bundle.

Something similar to incremental mode or update command of
archivers...
