thanks for that information. but what’s the alternative? building another naming system on top of aeternity like ENS on ethereum? 
I guess many people using the naming system would like to see subdomains being implemented.
another question regarding the pointers. I was a bit confused in this discussion:
I always thought the pointers behave like a key-value map. but in fact it is true they for a key (e.g. account_pubkey) multiple values can exist but only the last one is relevant right?
