@mfreed7 do I need to run anything recursive in the last step here? I briefly tried to make a demo with a slot assigned into another slot, but it didn't seem to work.

I guess I at least need to check if the parent is a shadow host, right?

I was hoping this definition could mostly stay in CSS and in DOM we could use the composed tree (which we use for events).
Perhaps having both concepts in DOM is useful, but early on we were fairly deliberate on the split and I feel like we lost some of the knowledge as to why we did things that way.

You want to return parent here, presumably.

What about children of a slot element?
