Dear Peter and Aftab, Extended communities are not transported in the Internet. So if I start new company and I want to sell IP transit, I'm competitively in disadvantageous position if I cannot market <myASN>:<action> traffic engineering policies to my customers. Sure I can use privateASN (and I must), but they are clearly less preferable on INET, and almost certainly won't cross many links.
I.e. 16b ASN is special and should be under more strict assignment policy, when living without BGP communities is hard.
