Could you provide some examples of some sites that need to apply such 
limits, and show how people are currently achieving this?

Are there sites that use JavaScript to achieve this now, perhaps by 
listening for click events on the checkboxes, counting how many are 
checked and then preventing too many being checked.  Or are there sites 
that count how many are checked onsubmit to ensure there aren't too few 
or too many?
