Besides which, once the flight control system version x.y is finished, the development tea doesn't then immediately start working on flight control system version x.y+1 (or worse, versionn x+1.0). It isn't as if NASA finishes a shutttle, and then immediately starts building a new, improved shuttle.
Every flight requires a new version of the primary flight control software and, because of the long lead time to prepare a version, they often have 2 or more in the works at the same time. At one time in 1983 there were 5 versions being worked on simultaniously.
Reliability in the flight control software for the space shuttle comes at a price. Their cost per line of code is $350*. That buys more quality than most commercial vendors can afford.
