I doubt it.
For the same reasons, really. People who already intend to thoroughly go over the input and output to use AI as a tool to help them write a paper would always have had a chance to spot this. People who are in a rush or don't care about the assignment, it's easier to overlook.
Also, given the plagiarism punishments out there that also apply to AI, knowing there's traps at all is a deterrent. Plenty of people would rather get a 0 rather than get expelled in the worst case.
If this went viral enough that it could be considered common knowledge, it would reduce the effectiveness of the trap a bit, sure, but most of these techniques are talked about intentionally, anyway. A teacher would much rather scare would-be cheaters into honesty than get their students expelled for some petty thing. Less paperwork, even if they truly didn't care about the students.
Countries willing to pass on a US patent to China stop getting the chips (or, in this case, chip-making jobs, realistically, but that still hurts)
Also Taiwan doesn't wanna help China and even if a US sanction was just an excuse to hurt China and get away with it they'd probably do it.
Edit: in this case, this chip is "foreign-produced items [...] that are the direct product of U.S. technology or software", according to the article. I feel it was implied but clarity is always good. US technology, used with permission in a Taiwanese good, and that permission could be retracted.
