Right, but these are the exceptions for a reason. Something life is exposed to only every hundred(s) millions of years or so is so infrequent that evolution selects against so long as it introduces inefficiencies (and nothing is free). Evolution is an extremely dumb optimization process, and will simply drift away from rad-protecting features as soon as the event is over.
