angular2 uses it. I have an additional node. considering I change a upper shadow-root which has 50+ shadow-roots it's 50 more node's. We have lists which have a component per cell and per row which is like 100x10 lines. That would mean 1000 x 2 node's more? Changing the whole table would probably be way slower without the inner shadow-root's.
