Question one is: do you still stand by that earlier assessment?

It's what I was hoping would work, but apparently font-lock rules are
inevitably called from different narrowings (at least in some, edge-case
scenarios). So to be ironclad, CC Mode has to call 'widen' its some of
its font-lock-keywords matchers.
But that breaks the narrowing applied by mmm-mode in its aggregated
fontification function.
