I was thinking of it as analagous with the "perl" directory that
currently exists. So the "python" directory will contain library code
but scripts can live wherever is most appropriate.
One way of looking at it is: could the user want to have this installed
for all available versions of Python? For a script, the answer is "no"
because they will call it and it will just run. For libraries, you want
them to be available with whatever Python interpreter you happen to be
running (assuming that it is a version supported by the library).

I don't think such a dependency is a bad idea in the longer term. If a
"Git Python library" is developed, then at some point most people who
have Git installed will have some version of that library - it becomes a
case of perhaps wanting to limit yourself to some subset of the library
rather than just not using it.
In fact, git_remote_helpers has been available since Git 1.7.0 and
contains a lot of functionality that is more generic than its name
