Wow, I didn't expect that.  I was instead about to ask for details about
the mentions of `font-lock-fontify-block' since I view it as a command
which "should" be a no-op (barring bugs, obviously).

I'd be quite interested to know more about those existing use cases (they
may point to other misgivings of mine, as well).
