Including the explicit keyboard support for each component is extremely helpful for contributors and consumers.
Intent is to eventually port this information over to the docs site.
We will be explicit about what a11y attributes (e.g., role) can be modified by consumers or not.
E.g., aria-label depends on the use case, whereas role="img" probably shouldn’t change depending on the use case (i.e., role attribute should not be overridable by consumers).
