Well, it doesn't WFM for cygwin binaries. I used the following command to
determine the Subsystem value from the optional headers for every exe in the
/bin directory of my cygwin installation:
find /bin -type f -name \*.exe -exec echo echo \{\} \&\& objdump
--all-headers \{\} \| grep Subsystem \| grep -v Major \|grep -v Minor \;
>temp.sh
[followed by "chmod u+x temp.sh ; ./temp.sh", of course]
and the only files which show up as "Windows GUI" rather than "Windows CUI"
are checkers.exe, fluid.exe, glpuzzle.exe, ipc-daemon2.exe, mandelbrot.exe,
rubyw.exe and wish84.exe. So it wouldn't spot my earlier example, insight.
Then I tried it again on the files in /usr/X11R6/bin. It only identified
run.exe, Xnest.exe, Xprt.exe and XWin.exe as GUI apps. That seems like a
way bad false-negative ratio to me.
However it should be fairly reliable for pure 'doze apps.

It's a matter for the cygwin bash/zsh maintainers. On the whole cygwin
apps maintainers tend to prefer not to maintain cygwin-local patches for the
long term, so it's liable to come down to the attitude of the upstreams in
the end. But the matter is entirely technically feasible. PTC?
