If the ring gear appears to be in good shape I see no reason to replace it.
I wouldn't say it is standard procedure to replace it -- only when
necessary, at which time it is generally pretty obvious.

I don't see why you couldn't just tap it, but might as well wait until the
engine's apart and cleaned up and it's accessible in case drastic measures
become necessary. Worst case, the crank's toast for other reasons, so you
wouldn't have wanted to waste time on it.
