We're talking about adding API for non-HTML. What's already better supported on
HTMLElement is of little relevance here.

I don't think so. I think it's the presence of the "HTML" in innerHTML that
raises the question of whether its action is less generic and contains some sort
of HTML bias. For someone paying attention to HTML5 development that may or may
not be a question, but the number of web authors out there who are is virtually
zero in the grand scheme of things. To them, not making things counter intuitive
matters IMO.

Sure, people will figure lots of things out if they *have* to. But why should
they? Why add unnecessarily to the learning curve and why make the platform
wartier and more unpleasant to work with than it needs to be? It doesn't do
authors any favors.

It's "already here" in the sense that it's already in HTML, but it's not
"already here" in other languages like SVG, so it seems like it's not "already
here" in the context in which we are discussing. And I don't think it adds
"complexity", I think it smooths out the user experience and provides more
intuitive API.

Anyway, we're getting into "I think this group of third party people think X,
and you think they think Y". I guess we've both got different experiences of the
"general author".
