Hi Pengpeng, I think it boils down to arbitrary choice: we either need to discard the head or the tail of the list, and the current implementation discards the tail. I think the most common way to order nameservers is by decreasing priority, so the current implementation is the least surprising to me.
Do you have a specific reason to ask for the other way around? Thanks!
