If Read-only set/UnmodifiableSet doesn't implement the Set interface, you won't be able to use it for functions with arguments of type Set. You won't be able to cast back to a Set because a ReadOnlySet isn't a type of Set.
The only way this would work is if java.util.Set extended ReadOnlySet/UnmodifiableSet, and that will probably never happen.
