Comment (by wlodekwencel):

 Relay-Forward message tested with the rest of not allowed options in
 message:
 client ID
 server ID
 preference
 time
 option-request
 status-codes
 rapid-commit
 reconfigure
 reconfigure-accept

 RFC 3315, table A "Appearance of Options in Message Types"

 According to RFC 3315 section 15, those messages should be discarded, or
 in some cases replayed with statuscode UnSpecFail.

 It looks like Kea6 doesn't checking messages for not allowed options.

 To repeat all those cases plz use Forge project and run all test tagged
 with 'relay_invalid', also I attached wireshark capture for all those
 tests.
