Is there a reason why "Revolutions" and "Radians" or "AngularDegrees" are not CompatibleUnitQ?

I understand that keeping a consistent unit framework across multiple domains is complicated and not everyone will be satisfied with the choices made, like when people ask why "Radians" are not dimensionless in the Wolfram Language.

So I suppose there is a probably a reason why both

CompatibleUnitQ["Revolutions", "Radians"]

and

CompatibleUnitQ["Revolutions"/"Seconds", "Radians"/"Seconds"]

return False, or similarly with "AngularDegrees" instead of "Radians", or a time unit different from "Seconds". It does surprise me as there are multiple domains in which this unit conversion would feel natural.
