I believe we are saying the same thing here.  That's what I meant by a user not
currently being able to get the feature on some given window system.

The point is that that doesn't mean that some other window system might not
provide such a feature, or even that a future or past version of the same window
system might not provide it.

IOW, let's separate which features Emacs allows from what some window managers
might support.  Certainly we do that in general; there are some window mgrs that
do not support some features that Emacs supports.

Sorry, I don't follow.  What does that have to do with what you or I say above?
