Three things change.

1) Dnsmasq loses the ability to provide service on dynamically created
interface. If an interface doesn't exist when dnsmasq starts, dnsmasq
will not be listening on that interface when it comes up. Similarly if
an interface changes address.

2) --interface=<non-existent interface> becomes a fatal error.

3) The semantics of -interface changes. Without --bind-interfaces,
--interface filters on packet arrival interface. With --bind-interface,
--interface=<iface> becomes equivalent to --listen-address=<address(es)
of iface>. So, on a multi-homed host, with --interface=<eth0>, a request
sent to the address of eth0 which arrives from eth1 will be answered
with --bind-interfaces, but not answered without it.
