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.

No need to apologize, your input is always welcome!
