You make a good point! There are many common input configurations that will come up again and again, as forms and other types on input (like maps as you mentioned). How can we solve for that?

Maybe a solution would look like the server expression a more general intent -- "shipping address", and leaving it to the client to determine the best UI component for capturing that information. Then the server will need to do its own validation of the user's input, perhaps asking for confirmation that it understood correctly.
