I wouldn't ever be transmitting them around the place, unless also
allowing users to enter them. But I have done exactly that - a
validator system that lets you put a header with a regex, and then
string content below that. That IS one advantage of the regex.

However, that's a very VERY specific situation. If I'm not asking a
third party to provide the match condition, then that's not a reason
to go regex.
