It isn't a big deal.
Only time consuming.
Yes, I've done it, as you can see in my sig pic.
Yes, I put my 17 yr old daughter on it with me.
Yes, I ride it just as hard as I rode it straight from the dealer.
No, I'm not concerned anything will "fall off."
This entire "broken frame...MOCO should take it back...dump it" thread is starting to be comical.
It's a GD warranty claim, nothing more.
No more than a wrecked bike getting a new frame.
How many of you have ever worked production line work?
Ever missed something on what you were putting together?
If the OP is concerned with the dealer that'll be making the repairs, then perhaps he should find another dealer?
It's not written in stone that the dealer that sold this bike has to do the warranty claims on it.
