Should reflection be a native feature for web components

HTML defines different kinds of reflection between attributes and values. It feels like these should be exposed in a way that could be used on web components.

We should talk to folks to see if this has been investigated, and what the blockers are.

Start by reviewing the HTML-defined forms of reflection between attributes and values and checking whether web components already expose related behavior. Investigate prior discussions and identify the blockers; done would be a documented conclusion about feasibility and next steps, rather than a specified code change.
