I do agree that the rename is probably more often desired.

Yes, I think that is largely a correct impression (although I think
Linus has spoken out against directory renaming in the past, so there is
at least a little bit of conscious effort). I suspect the right sequence
of steps to implement this would be:

  1. write a proof-of-concept that shows directory renaming after the
    fact (e.g., take a conflicted merge, scan the diff for directory
    renames, and then fix up the files). That way it is available, but
    doesn't impact git at all.

  2. If people think it is useful, build it into the diff and merge
     machinery so that it can happen automagically, but make it
     optional. Thus git fully supports it, but the policy decision is
     left up to the user.

  3. Make it the default if it is the common choice.

So we just need somebody to volunteer to work on 1. ;)
