I've started working on a patch to add `:options' flags to mode hooks, such as 
`imenu-add-menubar-index' for modes supporting imenu or `eldoc-mode' for modes 
supporting eldoc.  In that process I started adding `defcustom' for hooks to 
modes which lacked one.  Since I'm currently busy with real work I stopped 
working on it.  If there is interest I could push the current state.  But this 
could of course also be a motivation to add such a feature to `define-derived-
mode'.  Although I'm not sure how to best represent it.  A `:hook-options' 
would probably miss the point.  Maybe a `:supported-minor-modes' option?
