No idea. Asking ‘why’ about PTC products usually doesn’t lead to a satisfying answer.

Why can’t holes change size via relations (1/2-13 to 3/8-16, etc.)?
Why can’t holes change size via a family table?
Why can’t thread depth be controlled independently?
Why can’t drill depth be controlled independently?
Why haven’t the hole tables been updated/expanded since version 24 (22 for UNF)?

… and on and on.
It’s no wonder people are forced to create their own custom holes and the tools to use them.
