Indeed, and I expect the same problem to pop up in other places.
Which is why I think the problem should be solved in those modes which
allow execution of arbitrary code via file-local variables without any
security precautions or other limitations, at least under user
control.

No, it's the same problem, and I don't like the proposed solution for
the reasons explained above. I think we need a different solution.
