Yes :)

Beyond this specific instance, I think the principle you outlined is
sane: Chef shouldn't try to do what you mean, as more often than not
it would violate POLA.
A warning can and will be ignored, and may lead to unexpected consequences.
A failure on the other hand requires the user to pay attention and
either fix the underlying systems, or adapt the cookbook.
