For the record, I've been using Cygwin for twenty years or more. For
that entire period the recommendation has been not to install in C:\ or
the root of any other drive. (I've been using UNIX since 1983 by the way
and Windows since version 3.0 not that it makes any difference to the
discussion.)

Which can be accessed using //host/path (using S4NFS or SMB) or via
Cygwin fstab mounts regardless of where Cygwin is installed locally.

You're not using a Linux shell. You're using a POSIX-like shell compiled
for Cygwin. It's different. For example '//path' on Cygwin accesses
remote filesystems whereas on Linux it doesn't.

If you're running a program on Linux it'll launch whatever it is
configured to launch.

If you're running a Cygwin program it'll do the same, which with
appropriate use of cygpath can launch Windows Explorer (explorer.exe) or
your browser. For example my EDITOR variable launches Notepad++ and 'git
difftool' launches Windows native KDiff3 and they work for any Cygwin
path not just my C drive, converting to Windows when assembling the
command line to pass to the native applications.

I think Andrey covered the rest of your arguments fairly comprehensively.
