I want to mention that the TryParse heuristic that we added in minimal API means we support these out of the box 😄

Hmm, your comment reminded me that we want to special case DateTime. The default DateTime.Parse (and I imagine DateTime.TryParse), formats the date to a server local time. We had to author a model binder in MVC to parse it as UTC. @DamianEdwards did some research on this: #11584 (comment)

We've moved this issue to the Backlog milestone. This means that it is not going to be worked on for the coming release. We will reassess the backlog following the current release and consider this item at that time.
