I was thinking of documenting this use of font-lock-fontify-region-function
in the new "multi line font lock elements" node of the elisp manual.
Do you think a separate hook is still necessary?

The way I see it, a separate hook would only really make sense if it were
a "normal" hook where you can place several functions, so that minor modes
can also use it reliably and easily.

I don't understand what you're saying here.
