Not storing branch name is an issue and Eelco should decide whether we need

provide any concrete usecase?

I'd add the following:

5) Possibility to comment old commits (e.g., "bug #n was introduced here").

This is a weak side of git (btw, can we make git clone git-notes?).

some dangerous things here.

Explain in more details, please. "Git *obviously* has no architecture" is
