Okay then, if no other opinions I'll ask AD if we should update with "If no reply for A query is received after ENR implementation specific timeout, after reception of positive AAAA response, the ENR MAY choose to proceed as if there were only AAAA record available for the destination." and publish -09.

Thank you for feedback,

Teemu

This 300ms is for difference on reply arrival times and hence should not depend much on access network latency. If the host sends queries in series, then it would be different thing. I was also considering reference to Happy Eyeballs draft: draft-ietf-v6ops-happy-eyeballs-07 , but thought maybe not..

I think that new wording is prudent. A and aaaa may be cached and refreshed separately.
