The important thing is that the Core is designed to provide you the tools to do what you need, not to add as much flexibility as possible for all use cases. Your use case is the edge case (Request.HTML is used 99% of the time to update the DOM with HTML fetched from the server). Even though your case is an edge case, there's an easy way to manage it: don't have the class evaluate the scripts and then do it when it fits your logic flow.
