Yes, that check is invalid as well.

In pfSense, we patched our dhcpd (4.2.8) to remove those two checks,
and PD is back to working correctly, as it did previously. There are
many configurations where it's impractical at best to meet this
validation. Agree with Christian earlier in the thread, and Jim, this
is broken.
