Sorry for missing the original question.

I'm a bit worried by the function relying on the fact that
default-directory is the directory of the repository.  Wouldn't it be
better to explicitly let-bind it inside the function?

A (perhaps safer) alternative for emacs-28 would be not to use
:(literal) for remote repositories.  What are the disadvantages of
that?
