I would think that you wouldn't need to wipe more than once. But I know when the ROMs came out that devs told us to wipe 3 times, you had to wipe 3x to get it to work. I know b/c that information was not readily available when I first flashed. Didn't work just wiping once. Was told to do it 3x and success.
Also, it brings to mind something like Metamorph. Often, I've had to redo an installation b/c it didn't do everything the first time.
And there's Titanium Backup, which for me almost never restores everything on the first shot.
Regardless, this sounds like a potential geek war in the making, so I'm def sticking around just in case. lol
