Because Junos BGP implementation is coming from "hey my home server can now
talk bgp" so some of the things that would be deemed unthinkable in a
routing system BGP implementation are normal in Junos, and what's worst
users don't seem to mind. 

Haven't you seen any new capability being advertised? That would be the only
sensible reason why to drop a session because of this. Though the only thing
I found was  draft-fletcher-bgp-inactive-path-00.txt
