Hole for water line too close to edge of stud / drywall?

I have a question about what is the minimum acceptable distance from a hole to the edge of a stud where it meets drywall.

Recently, I was helping do a remodel and during the demolition phase of removing a ceiling, I noticed that a water line (pex) was awfully close to the bottom edge of a ceiling joist.. I thought, “wow! They were lucky that the drywall installers didn’t puncture the pex water line when they hung the ceiling drywall!” It got me wondering, how much distance is necessary from a hole to the edge of a stud, or in this case ceiling rafter so that a water line isn’t punctured by drywall installers.

Wiring and plumbing should both be centered in the stud. Sometimes that is not possible. For those applications a nail plate is used to protect the plumbing or wiring from wayward screws. You will usually see them around the drain plumbing in a bathroom since the drain line is so large and takes up a lot of space.

These plates get tapped into the stud over what is being protected.

If you really want to piss off the carpenters, at least the ones that care about their work, notch the bottom of some joists. There are specific notching & drilling parameters:
