Actually it is questionable if it is worse to reject a timestamp or just let it wrap. Rejecting a valid timestamp is a bit like "You don't exist, go away."

Actually the cutoff can be really different for each filesystem, not necessarily 2038. However, I maintain the above still holds.
Consider a filesystem that kept timestamps in YYMMDDHHMMSS format. What would you have expected such a filesystem to do on Jan 1, 2000?
