Just to chip in for the dozens of users I have personally spoken to that 
do have the requirement for nova-network to neutron migration, and would 
be adversely affected if it was not implemented prior to deprecating 
nova-network: raising this concept only on a development mailing list is 
a bad idea :)

If anyone is serious about not providing a proper migration path for 
these users that need it, there is a need to be yelling this for 
probably a few of summits in a row and every OpenStack event we have in 
between, as well as the full gamut of periodic surveys, blogs, twitters, 
weibos, linkedins, facebooks etc,
