If that's the problem, we could disable narrowing/widening in Info
mode. (I'm not saying we should, but if we decided to do so, it would
be IMO a better solution than a whole new infrastructure with two
kinds of restrictions.)

Actually, it happens to be a feature (more accurately, a basis for a
feature), both in Info and in Rmail.

But you will never be able to disallow widening completely, because
the primitives are not going to go away, and there's nothing to
prevent a motivated individual from invoking them, even if they are
non-interactive.
IOW, I don't see how the suggested duplicity will solve enough of the
problem to justify the added complexity. (For that matter, I don't
see the problem, either -- see my other mail in this thread.)
