rfc8415 also says that your client has to request multiple IA_NA and/or IA_TA and/or IA_PD in the same packet.  Is your Windows client doing that?  Once more, you can confirm with wireshark.  That is the first thing to confirm before you start pointing fingers at Kea and saying it won't support this or that feature.

In my experience, your windows client is only going to be looking for one IA_NA unless you have written your own DHCP client (maybe it will ask for an IA_PD if it has somehow been configured to be a router - i've never tried that).
