Ok, I'm still unclear as to exactly what advantage V2 has over V1,
besides that CRC insertion attack. (Not that that isn't good enough
reason to switch to V2.)

Changing StrictHostKeyChecking from "ask" to "yes" provides no
security advantage, as far as I can see. It just changes the user
interface slightly; you have to type "ssh -o 'StrictHostKeyChecking
no'" instead of just typing "yes" when prompted.
