Hence I don't think they could be added directly. For your specific use case, if you are asking if we need to add the 3 nodes "_acme-{host,wildcard,domain}-challenge" to the registry, I think that is a reasonable suggestion, since "_acme-challenge" presently exists, and may ultimately be superseded by your updated acme dns challenge draft. Note that there have previously been vigorous debates on the topic of more generally adding new application specific labels into that registry, and there doesn't seem to be a consensus for that at the moment. I'm sure other folks will chime in with their views. But I want to ping Paul Wouters specifically - since you are one of the expert reviewers for this registry and an author of domain-verification, could you express your opinion on the specific request related to ACME (a pre-existing entry in that registry) and its new scoped challenge specific labels.
