You could do them seperate of course, but using basic tools you add another hour or so of busywork just to get back to the area you need.
As far as the rust, of course surface rust doesn't matter, but it turns into actual concerning rust fairly quickly; my stock exhaust flanges were starting rust severely to the point of effecting function after just two winters. I hadn't originally planned to do the driveshaft at all, but going down there for the flywheel and clutch and seeing it with spots all over, I figured I might as well gain corrosion resistance and drop 10 lbs for relatively cheap.

I can see why you'd want to do it, but why do you make the assertion that while doing the clutch and flywheel, NOT doing the driveshaft would be an error... given the dismal actual realized performance gains, and non-exclusiveness of the clutch and flywheel relative to the driveshaft?
Let's be real it takes 10 minutes to take off underbody panels.
Add another 10 for driveshaft assembly if you're half decent with wrenching.
It takes a whole day or more for most people to do a clutch and flywheel job.
