Of course it won't be classified as not_found. It won't be classified as
anything, as it doesn't meet the expectations of any category.

Why? A classification only makes sense if it gives us useful information.
The "other" category has no other purpose but to support the arbitrary
requirement that status() needs to set one and only one bit. It is not
unreasonable for some entities to fall in more than one category, or in no
category, and the additional requirement that the categories are disjoint
and fully cover the domain does not seem to buy us anything.
