No.  `C-x n w' is not advised.  Nor is `widen' advised.  Nor
redefined in any way.

But again, I am not asking that you adopt my code or my approach.
The point is that users are not bereft of ways to return to a
previous restriction.  I answered the "problem" posed by Eli for
narrowing in Info.

I'm not even asking that you provide or enhance commands in
some other way, in order to, as I showed, make it easier for
users to return to a previous restriction.

I'm asking only that narrowing continue to be usable by both
users and Lisp code, in the same way, as a change in buffer
limits, rather than, say, a fiddle with overlays.
