It certain can be, if you know the exact orig commit.
Maybe I wasn't really clear here: I wanna do a fully automatic import
into a git history (optimally, by just having package name and version).

It's not entirely trivial, if the maintainers are doing wild merges.
(eg. w/ kodi). Even worse: reconstructing the change history ontop
of some given upstream release is pretty complicated and manual.
Merging down from upstream into packaging branch (instead of just
a simple rebase) turns out as bad idea here.

Yet complicated for me (especially regarding automating/CI).
Here're some examples on how my deb branches look like:
* canonical ref names
* always based on the corresponding upstream's release tag
* changes directly as git commits - no text-based patches whatsoever
* generic changes below the deb-specific ones
While gbp can help a bit here and there, it still far away from an
I'm currently helping myself w/ lots of mappings and import scripts,
but I'd like to get rid of maintaining all these little pieces.
