I haven't understood the 2nd part of your argument "Only someone interested in
COS would do that..."?
The problem that getPageNumber() solves is just what's in the javadoc. It
returns a "pure" page number, if there is one and -1 if there isn't a page
number.
Of course I don't know what the users are doing, but it could be that people
are using it to identify a page number based destination, and assign that
number to another destination, and to a PDF. Your intended change of the
behaviour would then result in an invalid PDF, as some destinations must be
object based and not number based. (It still works properly with Adobe Reader,
but fails PDF/A-1b checks)

> When creating a new bookmark with the same page number as an existing
> bookmark, the resulting destination is offset by 1 compared to the old
> destination.
> This results in the bookmark being set for the next page, which could be a
> non-existing page.
> I've added a class with an example pdf and my own output pdf. Run with
> argument of a path to where you have the pdf, including a trailing slash.
