Yes one can override policy rules and mine invalid SW transactions,
but that's not something that's likely to happen accidentally.

We don't depend on policy to avoid chain forks, policy however is
quite useful for making forks smoother since it can prevent miners
from accidentally mining invalid blocks and prevents users from
accepting invalid transactions accidentally.
This doesn't remove the need for consensus rule enforcement of course.
