That's already happening: code called via fontification-functions can
access the restriction via point-min and point-max. If you or someone
else can come up with efficient methods of using that information so
as not to go too far forward and back, we could consider removing the
lock from the narrowing. But we'd need to see the code first and
assess the resulting performance with long lines.
