In practice how does that work?

Let’s say they have replacement phone batteries that cost them $20 to make, does the EU limit their profit margins? Do they investigate to make sure it isn’t excessive? If the company tries to sell it for $50, is that too much?

Even then, Apple maliciously complied. They put shit speed usb-c, (maybe 2.0?) on all but the highest most expensive model.

You’re basically describing any of the electronic style coffee machines, good luck repairing a vendor lock-in optimized keurig or nespresso machine that scans your pods to validate their IDs before brewing.

Trivial is a strong word, but sure it’s trivial during static analysis. This is dynamic analysis and it’s a different beast.

That’s my initial reaction too.
