Thanks for the explanation.  I think I see what you are trying to do.

I don't see why changing `widen' would be the only, or necessarily
the best, way to meet that need (which is essentially to make a
sub-mode treat given bounds as if they were the buffer limits).

But you answered my question.  Thank you.
