Special paints and decals aren't a performance boost and is standard practice in many games, and as such is fine.
And yes, legacy engineered modules absolutely should've been removed/converted because there are still many (including some I have myself) that're significantly better than what's currently available. The reason I'm not posting about that (anymore) is because that happened several years ago and is considered a lost battle by most people who care. CG rewards are happening now, so now seems like the pertinent time to speak up about it.
A 6ly range boost is a significant improvement, I simply don't agree with the arguments above that "it's just 10% it's no big deal!" because as has already been mentioned for buckyballers for example that's a huge improvement and yet another module to police when organising community events. Just as 10% extra damage on a weapon, or 10% extra speed on drives would be extremely unfair in combat. However, even if it were as insignificant as you say - it's a point of principle; handing out time-limited performance enhancing unobtanium to a small section of the playerbase in a multiplayer game is widely recognised as poor form for good reason.
Look, I recognise this won't affect that many people and I know a ton of players don't play this game as a multiplayer game and never will. That's fine. I also recognise that some people aren't as competitive as others won't be irritated by the knowledge that their ships are permanently less capable than their friends'. I also admit that on one level I myself am pretty chuffed about my amazing FSD and I can perfectly understand why those that got it would want to justify keeping it and selfishly feelin' all glowy and special. It's just very questionable game design and there are other ways to drive player engagement than this.
