Essentially, yes, tough noogies.

The alternative is for the downgrade to execute,  and even tougher  
noogies.
I guess the decision is which set of noogies is tougher, or more  
acceptable.
I thought that if there were known corner cases where a downgrade was  
really, really a bad idea, yum could keep someone from shooting  
themselves in the foot.
Maybe the current behavior that doesn't attempt to protect against  
known failures is better.
