No, speed index would go up massively. A huge amount of lighthouse improves with server rendered content.

Likewise RSC is not nearly as free as other partial hydration methods. You send a full serialized copy of the tree and props over that has to be manually de serialized. This nullifies much of the benefit. Further, you still send the large (even larger now) copy of React. This is exactly why the comparison would be interesting to see, and why I brought up my concerns - it seems people are pretty under informed about this.
