Very much like the idea.

Depends, might be on instances too.
What we're talking about here is adding properties and methods on a custom
element, which is a subclass

Sure, authors can do anything

I think the ship HMS Ugly has already sailed, given a dash is
compulsory for the names of custom elements.

I'm unsure whether or not it is safe to use custom attributes without the
'data-', I've heard mixed opinions. How do we know that chosen attributes
won't someday be global attributes?

Same we we do today. Look to see how many pages use the attribute, find a

There is a difference in people not caring about forward compatibility and
polluting the global namespace, and not providing a mechanism to do it right in

If we're encouraging authors to define their own attributes, then we should
