Well then we'd better create something that _is_ for this.

With XBL2, that was relatively straight-forward: you just used the
'binding' property, and the binding's shadow tree replaced the element's
rendering. Why is it not the same with the Shadom DOM spec?
(Also, isn't the Shadow DOM spec part of "Web Components"?)
Anyway, if we don't yet have a good story here, we should write one. It
is, as others have pointed out, long overdue.

Well, there's not much that can be done about that, as far as I can tell.

Right. We never developed this very far, but with XBL2 the idea was that
we'd eventually let you override the binding of a '::scrollbox' pseudo, or

I agree it's hurting the Web. I tried to fix this with XBL2, but that
never went anywhere. Let's not forget this key use case in the Web
components work that is replacing XBL2.
