But it will break any scripts or selectors that depend on position in
the DOM. For that reason I expect many pages that include intents won't
"work fine" in UAs that don't have parser support. I agree with Henri
that it is extremely worrying to allow aesthetic concerns to trump
backward compatibility here.
I would also advise strongly against using position in DOM to detect
intents support; if you insist on adding a new void element I will
strongly recommend that we add it to the parser asap to try and mitigate
the above breakage, irrespective of whether our plans for the rest of
the intent mechanism.
