How would that be different from what force-mode-line-update does now?
It sets the update_mode_line flag for the window's buffer, not just
for the window, and it also sets a flag to prevent redisplay
optimizations that could get in the way of the mode-line update. What
do you suggest to do instead, and why would that be useful?
The problem with the update_mode_line flags is that they are
indiscriminate: the mode line shows a lot of data, each one of it
changes at different frequencies and due to different triggers. If we
want a finer resolution there, we need to make these flags not just
simple booleans, but enumerations with several values, or maybe
bitmaps. Then redisplay_window could be smarter about redrawing parts
of the mode line.
