Yeah.So that they make lots more noise
It is indeed an issue with some propellors or rotor blades - but not for normal flight. Some fixed-pitch, large diameter props can have the tips go supersonic at take-off power and low airspeed (especially when starting the take-off run). But the blade tips going supersonic reduced efficiency - the supersonic bits are basically turning power into noise
But what a noise!
