Just because Linux has taken the stance that their documented definition

POSIX allows leeway between implementations; this is one of those
documented places where they differ, yet are still both POSIX compliant
with their different choices. If your script is not robust to what
POSIX has already warned you about, fix your script.
If you really claims that Cygwin may and should be different and distinct from all other
existing POSIX systems (the more so that it is allowed by POSIX),
which is not the case. There are other systems where // is the network root.
Considering that due to the limitations of being embedded in Windows,
Cygwin cannot always perfectly mimic either Linux or POSIX systems, I
personally prefer the more generic approach to define POSIX as its model.
then it would probably be more obvious and clear to say this at the very begining, e.g.
"Get that Linux feeling (with all those differents and distinctions) - on Windows"
