A lot of people don't like them, but I'm personally a fan.
I like to listen for very faint signals, and a lot of the time the situation will be that I legit can't tell if a section of noise I'm listening to is just noise or a signal so garbled and faint I can't make it out.
However, if they're using a roger beep, that often enough is just enough to stand out from the noise in a clearly identifiable way.
Bit of a niche use, I'll admit, but it certainly helps.
