I think it may be difficult to return all a noop for all implementations.
if the API implementation used the equivalent of WINAPI (stdcall) calling
conventions (callee pops parameters), a generic noop routine doesn't leave
the stack in the correct state.  On the other hand maybe only Windows has
this problem and all other implementations use caller pops parameters
instead?
