Plumbers trying to get framing inspection to fail intentionally or just hacks? Looking for input.

Commercial Steel stud framer here. In 20 years I’ve never seen plumbers run copper through studs like this. This isn’t a “one off” but how they ran it everywhere. If my framing inspection fails, my office already knows which direction the back charges are going to get everything back to code.

To each their own, 9 different ways to skin a cat and all that but this ain’t it. Do any plumbers out there spend hours cutting over sized squares out of the steel stud with a grinder vs drilling/punching out a 1.5” - 2” hole ?

First time seeing this and generally curious.
