This was discussed at the time, and the decision was not to change the
values those functions return, as we didn't see the need, and similar
display features don't do that as well.

Yes, there is.  From NEWS:

  Lisp programs that need to know how much screen estate is used up for
  line-number display in a window can use the new function
  'line-number-display-width'.

If this doesn't help you solve your problems, please tell the details.

Thanks.
