What's new is in Win10 SDK -
https://dev.windows.com/en-us/downloads/windows-10-sdk ... If you read this,
from anything there PHP requires only UCRT, and it is available by the
default installation of VS2015 (and receives the updates with it).

Anything you mention, say ws2_32.dll, user32.dll, kernel32.dll, etc. is
platform specific. PHP links to specific functionality set which is defined
by _WIN32_WINNT and other macros. Together with the fact that it uses the
same toolset and CRT - here it is. We build native binaries ensuring
specific platform functionality, universal apps and others doesn't belong to
that functionality. 

I'm really not sure what is the practical issue you see.

Ok ... the correct abbreviation for what you mean is UWP. UCRT is however a
known term since some time
