Funny, when I saw this I immediately thought of UpdatePanel (I used to be on the ASP.NET team back then).
The motivation of UpdatePanel was not to provide the best design pattern for AJAX, but provide the fastest path to incremental page updates for ASP.NET Web Forms developers (with minimal code changes) - with all its limitations.
It makes a lot less sense to have a pattern like this in a modern SPA.
