I don’t know if it does, but that does seem likely.

Checksumming the inflated version makes sense to me, so that improved/varying
compression doesn’t matter (since it produces the same result).

Sounds like maybe GitHub doesn’t need to change anything.
If someone thinks GitHub *does* need to change something, I’d like to know
exactly what practical change is desired.
