That is germane, but it isn't what provoked me to blog...

Oops. Hoist by my own petard!

I stand by my blog post.

document.createElement() is different because there's an infinite number of
different HTML elements you can create, so a finite number of create methods
can't work.

Also, "document" and especially "window" are such large and generic interfaces
that adding dozens of new methods to them is undesirable. Canvas elements and
AudioContexts don't have that problem.
