I've checked the documentation and it seems to support it (in our case
at least, since we have direct connection - correct me if I am wrong):

" Note that in IPv6 DHCP, the hardware address may not be available,
though it normally is for direct-connected clients, or clients using
DHCP relays which support RFC 6939. "

Maybe the issue here are the respective fwbr interfaces inbetween?
