Entropy: That's just plain bad and lazy programming. The 3dfx version doesn't have this problem, maybe they should figure out how they fixed it. Because if you can't dodge the homing missles, and if you dodge them and they do a 180 and come back, that's just unplayable garbage. And why would the higher difficulty levels need to fly at higher "fps"? The original game didn't do that, so neither should Rebirth.
Well here's the deal:
In the original game many of the weapons were based on FPS (frames per second) which changes depending on how good of a computer you had. The better the computer, the better the FPS and so the harder the homers were to dodge.
Both the original game and the 3dfx version changed the difficulty of the homers depending on your particular computer's capability. So on your particular computer, you might experience the original, and the 3dfx version the same as each other...but it's something totally different than someone else may experience.
Rebirth has removed the variance in difficulty...it no longer depends on FPS. The different difficulty levels have the homers fly the same way that they used to at certain FPS settings. This way everyone gets a uniform game experience.
As an example...the homers now fly almost exactly like they did on the original game when I played it...simply because my FPS at the time were similar to what Rebirth has set the homers to fly like.
E.G. I used to play the game at 36 FPS on Rookie (FPS on the original changed with difficulty because on higher difficulties more projectiles were in the air at one time, and so FPS would drop). Rebirth has the homers on Rookie fly like they used to at 30 FPS (I don't know that...it's just for the example.) Therefore when I play the game they fly almost exactly like they used to.
Also I can still dodge homers on insane...granted they're very hard, but I still can. (And I'm not THAT good of a pilot.)

There was also a poll and the majority of the people said that the way the homers work now (0.57.1) is very close to the original.
