This mentions 0x0A00, aka Windows 10, for atomic rename support.

Similarly 0x0A00, aka Windows 10, for fdatasync().

And Windows 10 1703, for large pages.

Post Windows 8, the most annoying part is that manifests are required
to be able to check at run-time on which version you are running with
routines like IsWindowsXXOrGreater() if you compiled with a threshold
of MIN_WINNT lower than the version you expect compatibility for.
And each one of those things would mean cutting a lot of past support
if we want to eliminate the manifest part.  Windows 8 ends its support
in 2023, it seems, so that sounds short even for PG16.
