I'd need more specific proposals to say anything intelligent. To your
general question, my only answer is: this is what avoiding redisplay
of a window looks like in Emacs. (Perhaps you didn't realize, but
blinking the cursor on a GUI frame requires a redisplay cycle each
time the cursor is turned on or off -- that's why it stops blinking in
the window whose buffer is marked "not for redisplay".)

I think it's a one-time "eureka!" thing -- once you realize that this
is what happens, it will no longer be a surprise. (Note that the
warning popping up was a last-minute improvement: the original
implementation just silently stopped updating the window, because we
cannot signal an error from redisplay in a way that causes an error
message to appear in the echo-area.)
Again, practical proposals for something you think is better are
welcome.
