Based on the thread this morning around the NFVImpact flag [1], I saw this commit [2] into the neutron-specs repository to add an APIImpact flag. Given the discussion around NFVImpact, and the move away from it, I just wanted to bring this up in the broader community context and make sure everyone is on board with adding APIImpact before we start merging this and requiring specs to have this which change APIs.
