It's a special case that doesn't follow from the general implementation of the suffix adverb, and it does cause serious time saving visible for the user. This is why it should be in the Special Codes page. I think this agrees with the introduction on that page as well. Similarly, monadic (,/) is on that page because it's faster than what you'd expect from a naive completely general implementation of insert.
