The version number should not be part of the name.  The name should be
inherited.

You don’t need to override the “build-system” field.

Why can’t you reuse the inputs (which should be propagated inputs) from
the “python-dulwich” package?

Is the variant for Python 2 needed at all?  I’d rather not add it unless
a package depends on it.

Additionally, the same question as before applies: why use
“strip-python2-variant” here?
