That's to have any package using dnsmasq-base also ship /etc/dnsmasq.d/<package name> that contains:
bind-interfaces
except-interface=<interface>
For libvirt, that's for virbr0, for lxc that's for lxcbr0 and for network-manager that'd be the loopback.
This simply prevents dnsmasq from binding with any interface that's managed by another tool, avoiding the current conflicts we have at install and boot time.
Exactly the same as lxc and libvirt.
