I did not know BNS was publicly known so apologies for playing stupid. Of course BNS is at least designed for this specific use case. So this particular error, which imo is schema validation related, is not likely to occur. I am sure some seasoned Google SREs have a good grasp on what would happen if BNS was spitting out junk, but my guess is it would at least cause outages of some kind if not crashloops.
