I think the concern is that if the other device shows back up later something
bad could happen. (Such as mirroring from the newly put back device over
the top of the fresh install.) I don't know if that is a real possibility,
but I can see why people might have concern.

Well I think so, but the anaconda guys don't.

They don't consider a 1 element raid 1 array as a valid array and are worried
people will think they have redundancy when they don't.

The bug below gives a pretty good look at the various viewpoints. I think
I have seem some other similar bugs, if you want to look for more:

Also there was a thread on the anaconda list:
