Seems like you don’t really need to fork the system until someone applies DOB field in a meaningful way.
Even in such a situation, I would suspect the short-term solution is simply a patch or crack to neuter the functionality that the DOB field is supposed to implement. A full fork seems unnecessary, even counterproductive, since it would define your OS as meaningfully distinct (and noticeably out of compliance) with a standard installation.
