Because it is not clear, to me, what specifically the semantics of
this protocol is. I wrote it to support MacOS calldll. I cannot see
applicability beyond this API.

One of the strength of OO and polymorphism is precisely that users can
freely extend the protocols that their objects support, without
requiring *all* objects to support the protocol. A standard protocol
should be clearly useful cross-platform, for many different types, in
different applications.
