OK, thanks.

Gregory, we don't really need to be able to make such "locked"
narrowing from Lisp, do we?  If we don't, my suggestion is to make a
3-arg C function whose guts is the current code of Fnarrow_to_region,
and then have Fnarrow_to_region call that with the last argument nil.
Then the changes in the byte compiler, byte-interpreter, and
native-compiler can be reverted.

If we do need to have a 3-arg version exposed to Lisp, a separate
DEFUN is probably the best alternative.
