Hmm. Well, kidding or not, that could be useful (yes, I know that many
people will consider it utterly unnecessary :-).

I'd love a defhook that would get a ":hook-type SOMEVALUE" keyword
argument and would do

  (put my-hook 'hook SOMEVALUE)

where SOMEVALUE could be as simple `t' (normal) or `special', or
perhaps something more sophisticate indicating the expected use
(number or arguments, whether it will return something or not).

No, I don't have a use case for the "more sophisticate" case (though
it could conceivably be used by add-hook to check validity of
functions added). But certainly having all hooks marked with a
property would have uses, the first one getting rid of
`unload-feature-special-hooks'.

Just dreaming,
