It's just an interface. Just because it has "HTML" in the name doesn't 
mean that it involves implementing part of HTML. A rose by any other 
name and all that.

Two things:

    Other languages can inherit from HTMLElement too.
    Consistency empowers users.

If you move innerHTML to Element, what happens to all the other useful 
things such as outerHTML, insertAdjacentHTML, dataset, hidden, style... 
? HTMLElement is the basic unit that I'd expect all elements in a 
browser context to support.

Conversely, placing it on Element means that it becomes available in 
contexts in which people don't normally see it, such as regular server 
DOM stuff. That strikes me as weird, and possibly problematic.

I'm not saying that SVG is HTML, but at the very least in a browser 
context, even when standalone, it really should script in the same way. 
Libraries should Just Work. Developers shouldn't be surprised. Ideally 
SVG should inherit as much as possible, and only focus on defining the 
things that make it special.
