It needs to work under X11 as well before I'd consider integrating the
feature.  BTW, another detail is: does this property mean "stay above
every other GUI window", or "stay above the current Emacs frame", or
"stay above all other frames owned by this Emacs process"?

The latter seems more useful.  The former is probably what your
code does.  In X11, there's a feature which could do something like
the 2nd option, which is to mark a frame as being "transient", in which
case most window managers will try to keep it "above its parent window",
at least if that transient window is sufficiently small.
