My post replied not to your proposal but to Juri's statement (which you clipped,
but I've put back, for context). And Juri did propose removing that possibility.
He said that users should not be able to use a command to widen or narrow the
buffer outside of the current node.

In the bug #5839 thread, Eli argues that users should be able to do that, and I
agree.

IMO Juri did, by saying that user narrowing and widening commands should not go
beyond the current Info node.
