On the other hand, I think enabling AAAAs for be.pool.ntp.org would also cause a net benefit. Assuming that all of the 30.28% IPv6-enabled users in Belgium are also IPv4-capable, they now are sharing the 16 IPv4 servers in be.pool.ntp.org with the 69.72% non-IPv6-enabled users. 30.28% of 16 IPv4 servers are 4.84 "servers". That's a smaller number than the 5 IPv6 servers in be.pool.ntp.org, so by enabling AAAAs for be.pool.ntp.org those IPv6-enabled users would get a sightly larger pool of NTP server capacity available to them. It would be beneficial for the non-IPv6-enabled users in Belgium too, because they would not have to share the 16 IPv4 servers with the IPv6-capable users any longer. So in summary I think it seems safe to returning AAAAs for every single country-specific pool.ntp.org zone, Belgium's included.
