kea logs lease renew as prefix renew

In my test I do not have pd configured anywhere, clients are not requesting this but on renew kea logs

INFO  [kea-dhcp6.leases/195830.140468334618368] DHCP6_PD_LEASE_RENEW duid=[00:01:00:01:26:7d:fd:da:00:0c:01:02:04:72], tid=0x4deb: lease for prefix 2001:db8:1::1aa/128 and iaid=1 has been allocated

isn't this message a bit confusing?
