I would take a look at the test-cases for git-subtree.sh, which document some of the kinds of issues you will encounter. They may help you test compatibility.

Anything you can do to limit breakage to "opt-in" points-in-time only would be greatly appreciated.

You can name it and develop it however you like. No need to ask permission here.

(For the record, I'm also not the maintainer of contrib/git-subtree. I've just been trying to fix a few issues with it.)

If I were writing it, I would give the new program a different name but perhaps provide a "compile-time" way to set it to "git-subtree" instead. My reason for this is that it may need to exist with the legacy script for awhile, and it's good to be able to tell them apart.
