That said, it might make for easier debugging if the reftables file
declares the size it assumes.

If there is a mismatch in size, the reftable will look completely
corrupted data.  I think this will be a bad experience.

Yes, but I think it would take a bunch of other failures to get there.
And it's true of all of the other parts of Git, too; the master switch
is a config setting that says "I'm a sha-256 repository".

That said, I'm not at all opposed to a header in the reftables file
saying "I'm a sha-256 reftable". We shouldn't ever see a mismatch there,
but that's what I meant by "easier debugging".
