Okay, this sounds sound.

Let me be a bit more explicit about my wish: I vote for the prefix arg 0
to widen because this fits to the logic to view the whole file as level
0 subtree.  With this perspective on the feature the effect of a numeric
prefix argument is clear as day:

...
C-u 2 M-x org-narrow... => Narrow to the level-2 subtree containing point.
C-u 1 M-x org-narrow... => Narrow to the level-1 subtree containing point.
C-u 0 M-x org-narrow... => Narrow to the level-0 subtree containing point.

The last line stands in opposition to the current behavior.

C-u 0 M-x org-narrow... => Narrow to the level-1 subtree containing point.
