This approach might be aesthetically displeasing, but it works just fine. That can not be said generally. Reason for this is that the RR with an underscored prefix MIGHT end up in a different zone than the record without. This implies that two records with the same owner and different RRType MUST be in the same zone, while a name without and one with prefix MIGHT NOT, where also one of the zones is signed and the other is not.
