Comment (by TimothyBlynJacobs):

 Hi @ryankienstra,

 The idea of passing just the attributes as the JSON/POST body directly is
 interesting. But it isn't consistent with how the REST API generally
 handles parameters. `WP_REST_Request::get_param` will traverse all of the
 parameter locations looking for an attribute.

 Besides the inconsistencies, this would cause breakage if a block had a
 `post_id` attribute for example. Since it would fetch the value from the
 attributes, instead of the URL.

 Instead, we should just expand the accepted methods to include
 `WP_REST_Server::CREATABLE`. And then attributes can be passed in the body
 nested under `attributes`.
