I don't remember anything about the reuse work.

Yes, I seem to recall the original reuse work was done on a branch,
so what we see on the main branch is probably just a stub.

Does anyone happen to have a copy of the old CVS repository?
I thought I had a copy as it would have been used for the git migration,
but it's not on my current machines.
