I'm not GP, but I would love to understand this issue in more detail. Do you happen to have a good link for me to read about what has been tried and why it failed?

Perhaps it's a naive solution, but I would imagine that much of that could be solved through deferring to component hierarchy and enabling a way to assign things more specifically when defining the components in the CustomElementRegistry. I recognize your username and I realize that you have spent a lot of time thinking about these problems, so I would really appreciate whatever insight you have to offer. Thanks!
