[spec-reviews] Sketch out proposals for event synthesis/flow and reusable a11y behavior (#63)

Per F2F conversations with @chaals and @travisleithead at the July Berlin meeting, we are going to sketch out design alternatives for low -> high level event synthesis and reuse of behavior and ARIA roles/states for new elements (i.e., avoiding re-creating all of the infrasturcture to manage focus/assistive state for everything that's button-alike).
