One could argue that the surprise is your fault. ;-) You asked
to widen to the full buffer, and that's what you got. Presumably,
if you ask for that then you want the whole buffer (whatever that
might be), and in this context presumably you know what that whole
buffer is (an Info file). If not, you shouldn't be using `C-x n w'.

Need not? A user of `C-x n w' should have some expectation that
what s?he sees is not the full buffer, and s?he should not have
a false preconception about what the full buffer might be like.
On the other hand, if we take your view about surprise here
then the issue is more general: `C-x n w' could be surprising
in any context where Emacs narrows a buffer by default.
Taking that into account, it should perhaps be the case that
`C-x n w', just like `C-x n n', should have property `disabled'
set to non-nil by default. That should remove your surprise.
(And it's not just an "internal implementation", IMO. Not every
Emacs users needs to know that Info uses files and display of a
node narrows to part of a file, of course. But that information
is available to users, and they can make use of it.)
