But if one of the questions is whether an Emacs user

I have code that lets you incrementally move a frame
up/down/left/right, including wraparound or including
the possibility of not wrapping but continuing till
the frame is entirely off screen.

I don't see anything wrong with _allowing_ someone
to position a frame off screen.  Why they might want
to do that is up to them.

I can see the point of your argument. After all, this is how Emacs work today, and most people have been fine with it.

However, I don't feel 100% comfortable with the current situation.

The main issue is people with laptops connected to an extern monitor. When the external monitor is disconnected, Emacs might land off screen. I would imagine that most people would prefer that Emacs would be moved and resized to fit in the screen of the laptop (as I imagine, most macOS application behave).

Secondly, I miss an easy accessible method to move off-screen frames into the visible parts of the display. On macOS, the menu is always accessible even if the window isn't, so the obvious place would be a menu item like "Collect Frame" (I noticed that "C-x 5 c" is unbound) -- it could be placed after "Delete Frame" in the "File" menu.

If that question is not in fact being raised in this
bug discussion, then please ignore this intrusion,
and sorry for the noise.

No need to apologize, your input is always welcome!
