Forgive my ignorance on this, but by resources are we talking about API
resources? If so I would hate V2 to be in the names because backwards
compatibility means keeping that around. If they're not API resources,
then if we named appended the resources with V2 right now, will we be
able to remove the V2 once V1 gets removed?
Thanks,
Brandon
