It’s not a corner case when you have to enforce it.

Someone will end up in the middle and then you’ll be responsible for accepting or rejecting it.

The bulk is obvious but the debate isn’t for the obvious.

But it doesn't. We have a problem. We can focus on addressing the problem without pre-adjudicating every hypothetical corner case.

If your "work" is mostly AI, and if you don't disclose it, it goes to /dev/null. And yeah, you can get into a debate that it's unfair to reject 51% but allow 49%, but that's how the real world works - otherwise, nothing would ever get done. You also get a DUI for BAC of 0.08% but not 0.07%. That's not an argument for putting DUI laws on hold until we can figure out a more perfect approach.
