Degraded means that all of the array elements aren't functional, not whether
there is still redundancy.

Yes.

In your case you could have dropped the number of elements in the array,
did the install and then bumped it back up again. If you only had two drives
you wouldn't have been able to, because anaconda also has a minimum number
of drives for each raid type. So even a complete 1 element raid 1 array
can't be used for an install. In the past I have patched anaconda to allow
this. There have been RFEs both for allowing degraded arrays and allowing
complete 1 element raid 1 arrays and both (well actually more since there
are duplicates of these RFEs) have been closed won't fix.
