I would perhaps argue that juniper's behavior is the preferable one. Remember the definition of this "drop the message I think is broken" not inherently "drop the broken message," it's entirely plausible that the message is fine but you have a bug which makes you THINK it's a broken message. There is also a huge difference between considering it a broken message and a broken session, which is what Arista did.
