OK, sdague agreed with the suggested new approach to make
server.networks a list or enum, so I'm working on that change this week.
I have a question still. Today you can specify a network uuid of
br-<uuid> and the REST API will strip the br- prefix. This is a
carryover from super old quantum behavior which is no longer valid with
neutron. With my 2.37 change I was killing that behavior, now I won't
technically need that anymore since I won't be going down that code path
So should I continue to try and fix this as part of the 2.37
microversion or just leave it as-is to avoid additional complexity in
