These “rare” cases where the domain is not resolvable when a glue is not present are the ones this draft is done for. So did you look how rare they were in your dataset? Being able to resolve instead of not resolving IMHO has value even if the number is not big. We all know that a lot of data in the DNS is garbage, that should not stop us from using the good data.
