I mean, that Windows special handling of .exe be invisible on managed
mounts.  So "equate" in that the Cygwin filename "foo" might be 
the actual file "foo.exe", but certainly not preventing a Cygwin 
filename "foo.exe" as well (which might or might have the .exe extension
as an actual file).

This would require that the coding of filenames allow the Cygwin 
filename to have an .exe extension, independently of whether the actual 
file has the .exe extension.  Doubtless "chmod" would need to be able 
to change the actual filename when a file is made executable.

As for install etc *not* assuming foo=foo.exe, that should be possible 
just by making "stat" not perform the translation on managed mounts.  
(Presumably Cygwin tools which perform special .exe handling, perform it 
when they encounter a file which one can stat, but which returns "No 
such file" on open.)

I wasn't aware of it, and haven't been able to figure it out in a couple 
of minutes of playing around and Googling.  How?

Certainly I observe that Cygwin executes .exe files differently; if I
rename a shell script to something.exe, it doesn't work very well at
all.
