I think you're right -- this would be something worth following up on. At least, t5304 doesn't cover this case explicitly, but when I tried adding an empty bitmap with a bogus name, I did see a "no corresponding .idx or .pack" error, similar to the stale .keep file.

I'd trust your (and Jeff's) knowledge on this far more than my own, but would it be a bad idea to clean up .keep and .bitmap files if the .idx/.pack pair are missing? I think we may have had a discussion previously on how things along these lines might be racey -- but I don't know what order the .keep file is created in relation to the .idx/.pack.
