I've seen that Templates and Slots are changing and so we should avoid them, but I'm curious what is going to replace the system? I ask because a system that I've made myself in Unity with VisualElements, inspired by XAML, was to setup a sub-type of VisualElement which can be provided a Type via UXML. This sub-type does a look up to find any Templates that have been mapped to the type and loads that template automatically. I'm hoping to see something like this built-in, I find it a lot faster/easier to iterate on and I'm sure many others do to. If not can we get some idea of where the replacement system is going?
