This looks good overall! I have a few more cosmetic comments, but the two main open questions are the ones from my last review pass on which I want to get some additional input.

I still think that having the knowledge of the state of a resource (even if it exists) may be challenging in a distributed system that has a non-strong consistency model.
However, I understand that some systems may benefit from this field, and therefore it should be allowed but optional.

I'm resolving the comments.

Just one small nit left!

For future reference, please don't force-push to a PR once a review has started, since that makes it hard for the review to see what's changed since their last review pass. Thanks!
