What about the mode lines of the other windows showing the same
buffer? They might need redisplay even if the buffer didn't change,
e.g., to show the current line number. Similarly with the tool bar
(if the buffer is shown in more than one frame).
If you made sure all these cases are covered, I guess we can apply
this and see if someone complains.
