As soon as you hit the bad sector, your rebuild fails and you are stuck working with backups!

I have no idea if the assumptions it is making are still valid.
Sorry, but the facts are wrong, too :-(
You're describing a hard error - where the sector is corrupt, and that's that. I'm describing a soft error, where "something" goes wrong, and the drive times out. The next attempt to read it will work fine.
But as you describe, the rebuild will bomb. At which point, the raid novice panics and all hell breaks lose. The fix is actually dead simple - just reassemble, with force if necessary. The rebuild will restart, and off you go ... :-)
The problem, of course, is that the larger your array gets, the more errors you can expect, and the greater the likelihood of your rebuild failing, maybe multiple times.
