Totally agree re: tagging. Parent project should tag.

I suspect however that you may find tagging coverage for contributed projects, though helpful, will be spotty at best; i.e. Boost.Contributed tag '1.0.0' (by some tagging naming convention). I'd highly encourage its use though. Meanwhile though a little more effort hashes can be mined.

Especially when there are breaking changes that contributors aren't necessarily ready to roll with yet. Modules can reference specific versions I believe (could be wrong, I am a git novice myself).

Anyway that's my git style guide two cents. HTH and good luck!
