Re: BGP Community - AS0 is de-facto "no-export-to" marker - Any ASN reserved to "export-only-to"?'

No, but most network operators also aren't NANOG members, attend NANOG shows, subscribe to NANOG lists. 


They're small outfits where there's between 1 - 5 total networking people. 


Circling back to earlier where I said there are almost 70k ASNs in use on the public Internet. Most of those operators 
don't have complex configurations. I'd be surprised if less than half of them had anything more than the most minimal 
default route configuration.

Do you have some empirical data on that? 

I don't know if it's more, or less. But as Charlton Heston said in "True Lies":
