Why?

I disagree on this. If you don't allow "required" on checkboxes 
nearly everyone will just write some extra JavaScript validation to 
do the same thing. It is simpler to just allow "required". It only 
really makes sense for the "terms and conditions" type checkboxes but 
they are certainly common enough to warrant consideration.

By the way, I don't see why one could not include radio buttons too. 
Write something like 

    If one of a group of radio buttons is required it applies to the 
    entire group (e.g. one of the elements must be selected before the 
    form is submitted, but not necessarily the one that has the required 
    attribute). Authors may want to force a selection by having no button 
    in a group pre-selected.

I don't see any problems with either of these but perhaps the 
implementors or others on the list do..?
