Historical reasons I think.  Early Emacs inspired a number of Guile
extension points, and hooks are a thing there.  (Hooks are not just a
list of procedures -- they're a settable place as well and a way of
running all of the procedures.)  Anyway I agree, nothing to shout about,
and probably something the manual should mention less prominently.
