I'm doing the same right now. I have a list of checkbox which can be  
either on or off for each of my elements, and I can't rely on the  
input being absent meaning it is off because the list is paginated  
and may not show all elements at once. That hidden input trick is  
quite handy.

I do.

What about adding a "value-unchecked" attribute instead:

     <input type="checkbox" name="foo1"
            value="true" value-unchecked="false">

In the absence of a "value-unchecked" attribute, an unchecked  
checkbox sends no input, just like the checkbox we have today.
