One area that I still struggle with is dyn traits inside of ECS components. Examples of questions that arise frequently:

Do I really need to use Arc here, or can I get away with using Box?
Under what circumstances do I need to use a mutex?
Do I need to blindly add Send + Sync + 'static to every trait declaration, or can I get away with just some of them?
I want to downcast the dyn trait in the component into some other trait, what's the best way to do that?

It would be nice if there was a guide which explored these questions in some depth.
