I think this makes sense. The major version number corresponds to your use of a better source. 1.x: broadcast. All the 2.x releases: Blu-Ray. So 2.0 would be your first release using the Blu-Ray source and 2.1+ would be refinements.
And then some day 3.0 would be new 35mm captures or maybe even a future OT release by Disney/Lucas, which will of course be imperfect somehow and the perfectionist in you will still have to tweak. :)
