This is cool idea, but honestly i don't expect to receive call if i run LN node.
EXCEPT, cloudflare? Why?
It should be P2P not P2 -> some big corporate entity -> 2P
Granted I didn't read why they are doing it or much else since I am mobile so it could be in 24 point bold text as the reasons, but to me that in general would be a show stopper.
I agree, direct connection or Tor are better option.
