I suspect you're making your problem a whole lot more complex than
it need be.

A fixups hook would be the usual solution to that kind of requirement.

That's up to the server admin, not up to any module.  If a server
admin sets an interpreter (such as PHP) as handler, that's their
business.

If your module wants to take control of a request then it can
set its own handler (or unset the handler to get the default).
But then it needs to document that it breaks normal configuration!
