The problem is that unless one is holding customer routes in a 
seperate VRF and dampen them there or take similar steps to 
segment, dampening leads directly to blackholes.  Even in that
case, failover within that VRF wouldn't work, as all 
implementations I've seen attack the prefix as the problem instead
of the path vector. Bye-bye alternate paths.
