The current conditions make it so that every library transitively reachable from a reload target (and therefore included in the DDC output) must be known in the client when `dartDevEmbedder.hotReload` is called.
While this is the case for pages running with DWDS, it's an unnecessary constraint. Some users may only care about reloading a specific subset of known libraries. As is the case in dart-pad when we only need to reload the main library as we know this is the only code that can have changed.
Any new libraries must also registered and initialized as this is new code not yet in the page. This would happen if a new import was added to the code.
