The rules are there to ensure that if the resolver see an algorithm it supports then it can validate the response. If you fail to follow the rules answers won’t ALWAYS validate. If there is one level of validation happening the validator should recover by trying other servers. If you have

Dear DNSOP, It's well-known that DNSSEC multi-signer setups are problematic when providers want to sign with different algorithms. In a hypothetical scenario where signing requirements would be relaxed, I have a very specific question about how resolvers should behave. Apologies for the
