The "squad needs to focus more on performance / stability and not parts" complaint is now, in my mind, null and void. The person making these parts is prokjet, who AFAIK does not know how to program in unity. He also specializes in space plane parts, which is why we are getting more of those parts. While porkjet is doing his thing the rest of the team (Harv, Ted, etc.) are working on Unity 5, a huge boost in performance and stability.
