That's true of all their repairs, very much like Apple in that sense, "Oh, your key popped off the keyboard, no problem we can get you a new laptop"
It's gotten better over the years, I think the Right to Repair crowd are motivated by these issues. I was there in the early days when people would bring their computer in and say "I accidentally deleted my mail directory last week, can you recover it?" and the managers would say "Sure" and we'd spend a week of 3 genius's time to often fail at the task. Over my tenure they got more and more conservative about what they could repair to the point where it felt like the scenario above. But they have also gotten better at documenting the things that can be repaired and making parts available. They have keycap kits now, no more scavenging DOA computers for caps.
Hopefully the same will happen to Tesla over time and not always go for the biggest part that could cause the issue being swapped.
