I actually kind of like that idea, as it makes the interaction between
old and new names much simpler to reason about.

And since old code won't know about the new names anyway, there's in
theory no downside. In practice, of course, the encoding may often be a
noop, and lazy scripts would continue to work most of the time if you
didn't change out the prefix directory. I'm not sure if that is an
argument for the scheme (because it will suss out broken scripts more
consistently) or against it (because 99% of the time those old scripts
would just happen to work).

Do you care about case-folding issues (e.g., submodules "FOO" and "foo"
colliding)?

I'm OK if the answer is "no", but if you do want to deal with it, the
time is probably now.
