RFC 6762 also opted to not formalise this other than for supporting earlier implementations:

https://www.rfc-editor.org/rfc/rfc6762#section-11

Digging the first draft of this had MUST:

https://datatracker.ietf.org/doc/html/draft-cheshire-dnsext-multicastdns-00#section-5

By 05 it was toned down to a SHOULD, and 04 mentioned about some older IP stacks not supporting IP_RECVTTL; that may have been the reason at the time to shy away from this strategy.
