True.  That's nice as a way of collecting all your source code in one
place.  Or a repo can have have somewhat-related projects, like a GUI
and a library used by the GUI.

The current plan is to keep branches.  So if your checkout was
out-of-date, you couldn't commit.  You'd need to update it, or create a
new branch at that point.

Technically speaking, allowing it to commit isn't hard, if we want to do
that.
