I would imagine you're much more likely to get something like a framing error from a noisy line than an overflow

Probably true, but if you're unlucky enough to have the noise generate a false START then your chance of getting OERR instead of FERR increases.

A false start will just generate a spurious 0xFF character.
Again if interrupts are not disabled for more than a millisecond, it will NOT generate an OERR.
