Is accessing a component's parent view in ember future proof?

Sorry for double posting, but then this might be the better place to discuss this question:

I want to use nested components like in Alex Speller’s form tutorial. This works fine for now, but as I understand ember components are meant to be replaced one day by real web components, which are meant to be isolated/encapsulated. As I understand, this would break such nested components. Should I therefore avoid this pattern as “not future proof in the long run”, or should I be fine using it?
