Re: Minimum viable custom elements

FWIW, I think that element upgrade is sort of fundamental to the usefulness
of custom elements. In a world where most scripts are non-blocking (that's
hopefully the modern world we should aim for), I'll effectively expect to
walk the tree anyway.

And if I walk the tree anyway, what's the point of custom elements in the
first place? One of the key features (at least, to me) of custom elements
was being able to harness the HTML Parser to instantiate your object tree.
If that's not going happen consistently, then I am not sure custom elements
are worth the trouble. IOW, if you're walking the tree, just do the work of
callbacks as you encounter dash-separated elements.
