Even a lot of pros foot fault during the warm-up, and I don't think you really are in a position to say anything to them in the warm-up. At that time, you don't know what they are going to do during the match.
I think warning people about FF during the warm-up is kind of inappropriate.
I mean, people do a lot of things against the rules in warm-up on account of how it is warm-up. They catch balls. They let balls bounce twice. They hit serves wide and long.
Wait until the match starts and then see if there are flagrant FFs. If so . . . well, do whatever you have the guts to do about it.
