If the conclusion is, after some reasonable effort, that there is no way to make syntax-ppss significantly faster in one way or another in such cases, and that there is no way to make font locking reasonably accurate even when it doesn't have access to the whole buffer, it might make sense to provide user options to fine-tune the behavior. But we are not there yet.Both conclusions lead to removing the applications of narrowing from handle_fontified_prop.
I have seen no effort whatsoever to make syntax-ppss significantly faster in one way or another.
