Explanation required : Why only direct children of the shadow host can be slotted?

[praveenpuglia]

Over at the CSSWG drafts repository, I asked the same question and was told that that's how the Shadow DOM spec is defined.

So, I couldn't find any explanation as to why it's restricted to only direct children. Should it be mentioned in the spec somewhere as a note or a reference link which expands on it?

Please tell me if I am missing something really obvious.

I think in part it was done because of performance concerns and in part to make the initial version a bit simpler to implement.
