And this is the point: dampening can actually lead to decreased network stability and 
non-deterministic behavior.  Granted, this behavior is exasperated by not deploying a 
common dampening policy across all ASes (which is the why RIPE-229 was written).

This would not be as problematic if dampening could be applied to a path rather than a 
prefix, since an alternate could then be selected.  But since this would require 
modifications to core aspects of BGP (and additional memory and processor 
requirements) it does not seem a likely solution.
