The documentation is old and may not apply to Win10 but it's still the
one
listed for UCRT compatibility :

This doesn't seem right.
If WINAPI_FAMILY == WINAPI_FAMILY_DESKTOP_APP, then
WINAPI_FAMILY_PARTITION(WINAPI_PARTITION_APP) is true, and
_CRT_ALLOW_API_FAMILY_DESKTOP never gets defined.
You're right. WINAPI_FAMILY_DESKTOP_APP matches both. So only
_CRT_ALLOW_API_FAMILY_APP is defined.
The goal of _CRT_ALLOW_API_FAMILY_APP is to only select API's allowed
for "apps" (WINAPI_PARTITION_APP), so the opposite of what
WINAPI_FAMILY_PARTITION (WINAPI_PARTITION_APP) provides. In the end I
don't use it.
So I only need to define _CRT_ALLOW_API_FAMILY_DESKTOP which should be
defined when we're not in WINAPI_FAMILY_APP. But the
WINAPI_FAMILY_PARTITION() macro doesn't allow selecting only
WINAPI_FAMILY_APP.
So in the end I need to switch the code to define
_CRT_ALLOW_API_FAMILY_APP and then hide some API's when it's defined.
I guess it would be ok if you'd change the #elif into #endif + #if.
