Eli, you’re fundamentally misunderstanding something:
1. Your mode updates the display.
2. Another lisp program does not know your mode has updated the display.
3. Therefore, the lisp program will not know to call line-number-display-width.
Your suggestion that other modes should “always” call line-number-display-width
is what... to run an infinite loop waiting for your mode to furtively update
the display and catch it then?
