We have those too. I don't indulge them.
Any approach based on everyone else changing their behavior (in this case issuing a warning) is delusional. I cut plenty of space when passing other cyclists though because you never know what they'll do. Or more accurately, you know that every once in a long while, one that doesn't realize you're there will swerve right as you reach them so you need to be ready for that.
