Once you're changing things, why not? Eliminate those toupee lines people report seeing, or continuity errors. Have a voice actor read in a Balok line so Sulu's line makes sense.
Not being sarcastic, here. I'd probably still prefer the old dvd's, but once you cosmetically change the Enterprise, a main character, even how she moves, why not change more? Didn't they change Sulu's chronometer? Stuff like that. Or "one to the tenth power" in Court Martial.
Why not make a new physical model of the Ent and shoot her under similar lights and film grain, rather than CGI? Just do it with what is currently the best tech. Change rank braids that make no sense. Keep going, once the cows are out of the barn.
