If no one uses it, removing it does not break userspace. Removal of features happen regularly. How many? Dunno, doesn't matter. If there are users they are usually willing to step up to maintain it, and that makes having parallel APIs not a problem (the old one becomes a wrapper). Furthermore UNIX/BSD faces the same problem with every other program that lives out of tree. (Which is the majority of them anyway.) Knobology is always an endless debate, yet also regularly done without much fuss, usually simply by what the maintainer(s) decide to provide.
