I’ve used them for almost 20 years in Ruby, several years in Swift. I do find them useful in those contexts.
I haven’t used the C2x version, but one thing I expect them to be useful for is self-documentation of enums representing bitmask values.

I used to do that, and wound up back using hex. Hex is easier to read for me, as I don't have to count the digits.
