Not sure why you consider that a problem.  That's the whole purpose of
installing straight from the VCS rather than from a tarball.

If you don't want your Emacs to use that work-in-progress feature
branch, then work on it elsewhere than in the VCS clone that was created
specifically to be used in-place.
E.g. use `git worktree`.

The option already exists, it's called `git worktree` :-)

Switching to "that model" wholesale would prevent the current use where
you can edit the *live* files.
