It doesn't actually seem to.

In any case, "only" dnsmasq-base is installed, since both 
network-manager (and lxc1) still depend on it, however dnsmasq 
instances are still being launched by both Network Manager and libvirt:

I only just realised the lxc/lib virt connection, which might explain 
things. I'll file a bug on LP.
