No.  You will get the full current Info file, which is what you
asked for (with `C-x n w').

> Hard narrowing will allow widening to original page in step (3).

What "original page"?  Perhaps you mean the current Info node?

What do you mean by "allow"?  Do you mean that `C-x w' will no
longer widen to the full Info file?  That would be a regression.

You should use another function if you want to return to the
current Info node in Info mode.  It is sufficient to hit `g'
and give the current node name.

No need for any new-fangled hard-widening feature for this
use case.  And no need to break the use of widening to get
to the full Info file.
