It's possible that someone thought it would be a really good idea if //p[1]
meant "every paragraph that is the first child of its parent"; but I have no
evidence for this, and if they did, then with hindsight they were probably
wrong.

LOL. Another "really good idea" was to make sure that self::* never selects attributes, and introducing the concept of "principal node type" to ensure that.

Just kidding. I think this was another unfortunate side effect, but not nearly as bad as //p[1], or as David pointed out, the confusion surrounding the != operator.
