That's a very bad way of stating it. It's perfectly possible, and "supported" even though there is no "use this thing" solution for it. The problem is that you can't rely on a full solution being usable by all browsers you want to target.
They all do the same thing fundamentally; the only differences are slight technical details and who is in control of the standard.
