We have a handful of single-purpose narrow-to-* commands already
(which I use frequently and consider to be more convenient than
"select region and narrow to region").  I saw this as a way to
add lots of new options with *only* a single new command.

The "C-x n" prefix is not crowded, so I don't think it's a
problem to add the new key binding; and the function itself
also acts as a very simple helper for users to define other
THING-specific "narrow-to-*" commands for their own use.
E.g. if someone wants a separate `narrow-to-string' command
then the body is simply (narrow-to-thing-at-point 'string),
which I think is nice.

And of course it supports custom/future THINGs for free.

I think it's worth adding for all those reasons.
