On what precisely do you base the idea that a mandatory transitive attribute of a BGP prefix is a "purely advisory flag 
which has no real meaning"?  I encourage you to reconsider that opinion - it's actually a useful attribute, much the 
way that MED is a useful attribute.  Many providers re-write MED, and apparently some re-write ORIGIN.  Neither of 
those is "network abuse" - it's more accurately described as "network routing policy."  As has been stated here before: 
your network, your rules.
