Hi Bryan, I think can answer this one.

The <h1> etc. elements already have a level, so aria-level would be a
direct conflict. Why say the level twice?

However, a button (native or ARIA) has no way to say whether it's pressed,
or pressable, or has a popup, without the aria-pressed/aria-haspopup
attributes.
