You need to supply the users of the callbacks/hooks, otherwise we can
not properly evaluate them, nor can we accept them.

I have been saying this for over a year, please submit ALL of the needed
parts for these hooks to even be able to be considered. Otherwise they
will just be ignored for the obvious reasons stated numerous times in
the past.
