I think it's fine when the parent and children are really tied together. I wouldn't use that from the main component to a really nested children for instance.

Let's say you have a "SearchComponent" with a "SearchButtonComponent" and "SearchInputComponent", I'm okay with using the strategy I suggested because using "SearchInputComponent" without its parent somewhere else in the code would be too risky so the encapsulation is still kept between parent/children.
