I'll bite: because a user could want to peek a few screenfuls
ahead/behind, while keeping the cursor at a point of interest, where
they can come back with any point movement (e.g. arrow keys) or by just
typing in ("Greetings Mister… *scrolls back up* Mackenzie, RET RET I
trust this Sunday afternoon finds you well…").

Granted, IME I rarely want to check out an arbitrary "full screenfuls";
I usually want to check out the end of the current function (C-M-e) or
look for a pattern (C-s); if that takes me off-screen, C-u C-SPC brings
me right back where I was.

I wouldn't begrudge users who'd prefer the behaviour Po suggests,
though.

I don't see how (what I understand of) Po's proposition could lead to
such catastrophic text Armageddon.  And in any case, Emacs's trusty undo
would surely come and save the day.
