This was useful when the hashes were first introduced, but wouldn't be
used much now. If we did need to change the hashing algorithm, (eg, move
to SHA1, or change which parts of a patch are included in the hashed
text), then it'd be required for that.

I'd say keep it in, since you've already done the work converting it :)

Cheers,
