FWIW, while I don't find the idea of attaching event listeners this way too
interesting (maybe I could be convinced, but event capturing is already
convenient for most of these examples), being able to say "#myform input {
autocomplete: off; autocorrect: off; autocapitalize: off; }" or "a { rel:
noreferrer; }" would be great.
Having it not apply changes dynamically seems weird, since it looks and
feels like CSS. It'd mean these two things--which look intuitively the
same, and behave the same with CSS--would be very different when parentNode
is in the document:
var div = createMyDiv();
parentNode.appendChild(div); // our attributes are applied
div.className = "foo"; // and we override them
var div = createMyDiv();
div.className = "foo"; // we set an attribute
parentNode.appendChild(div); // and it gets overwritten
Also, the behavior of the latter is different depending on whether
parentNode is within a document or not, so it's now also dependent on
whether, for example, "document.documentElement.appendChild(parentNode)"
happens before or after.
