Timestamps are updated as well. But I don't think wear-off is really a problem for any kind of normal use. It's certainly less of a problem than the need to handle a separate /dev partition and make sure that things are kept in-sync through OS updates. If you're worried about it you could get a larger card than you need and leave some space unused to give a bigger pool for wear-levelling.
