Even in the 1.2.0 APIset is has a lot more functions listed than Wine's .spec file. I wonder what Windows 10/SDK version was used to generate these spec files. Unfortunately that information is rarely given in the patch description. I've already complained about that poor traceability in the past.
Sorry, I don't remember exactly which version I generated this one from. I remember digging up these api-ms-win-core-*.dll from the system32 directory of some version of Windows, but in recent Windows 10, they are no such actual files there to inspect.
Alternatively, if it was generated from the SDK, it would certainly have been incomplete as the SDK would only have the function in one apiset DLL even though it exists in many.
I'll try to document it better in the future if I add more of these api sets DLLs.
