That's inconsistent, DHCPREQUEST, for instance if not logged if the host
is ignored. I've just added a patch to fix this in the development branch.

My feeling is that this is probably over-the-top. There are a lot of
dnsmasq applications where the extra functionality doesn't justify the
code bloat.
