Of note is that jamming attacks are mounted by routing nodes against other routing nodes, and a routing node will not *deliberately* attack a payment that goes through them --- doing so sacrifices the potential for fees. It still remains the case that accidents can happen, and Y could fail completely by accident and cause accidental failure. Indeed, if any mechanism to protect against channel jamming succeeds, then the remaining instances of apparent channel jamming will be accidental.
