The problem is that then you can't just use the one array to cycle through
the controls that won't be submitted, and if you do anything to the
controls while looping through them to make them be submitted or not, the
array will change length, which can lead to some strange bugs that are a
pain to debug.
It just seems simpler all round to have the one array and a common

Using the interfaces provided, it's certainly possible to create a tree
walker which is pretty simple and does this. Without a common interface,
though, you'd probably have to get a native implementation to do it
sanely. I'd hate to see what it would look like written in JS! :-)
