I think that is indeed a matter of opinion (and should thus be subject to
customization), but I don't think we should assume that recursive editing
invocations or long message scenarios are always short-lived.

That's not what I'm seeing here. When I run:
(progn
(run-with-timer 2 nil (lambda () (message "hi")))
(run-with-timer 3 nil (lambda () (message "")))
(read-from-minibuffer (make-string 3000 ?*)))
The minibuffer resizes once, when the read-from-minibuffer prompt makes it
grow to its maximal size; it then stays at that size as the short message
is being displayed, then restores the long minibuffer prompt without
changing size again when the echo area is cleared.

So if, for whatever reason, I have a timer function that displays a
two-line message once a second (so the echo area never goes back to its
single-line state), my follow-mode buffer will be and remain in an
inconsistent state until I manually resize a window, when it will go back
to a consistent state, but then if I cancel the timer (and the mini-window
shrinks) it'll be in an inconsistent state again, and the only way out of
that one is another manual window resize?
I think that last case is something we haven't considered yet: if I resize
windows manually while the mini-window is enlarged, they will be in an
inconsistent state when it goes back to normal, right?
