I do have an opinion on the subject, but still I don't understand what
your aim is, actually. 

At first we started talking about a set of hooks, and a way of
managing them, but now it seems to me you were proposing a different
way of managing hooks *and* extensions.

As David noted, I don't know if a list of extensions is really
expressive enough - or, on the other side, if it is creating strong
requirements on the basic functionality an extension *must* provide to
be 'listable' and thus usable... if I get this part of the problem
right.

For the general issue of having some kind of hook management, to be
used instead of LayoutModifiers, I agree with you: there are
operations our users may be willing to add to (or to remove from)
xmonad that should not be carried out at the layout level (XEvents and
logging being the main examples that come to my mind). Proper support
in the core should be provided in my opinion.

I totally agree with David that starting with a contrib module should
be the preferred path, though.
