Jim,
 
it's well understanable why you'd like to have ACCEPT_OWN capability.
However the problem you're trying to solve is more global than the
solution can address. ACCEPT_OWN may solve issue for some networks that
follow certain rules, but there will be still those with different
network design but similar problem and ACCEPT_OWN won't address their
needs (e.g. with client-to-client reflection disabled). Such networks
will then go on and design yet another solution for the same problem. 
 
I believe it's not optimum to modify core protocol functionality just to
address special case scenarios, in contrary - protocols should be more
generic. Couldn't the problem with building extranets solved in some way
that wouldn't require modification of the fundamental BGP functionality?
One such possibility could be to add a new address family to BGP that
would redistribute import/export policies among all routers within
arbitrary boundaries. This way you don't modify core protocol and people
could take advantage of new functionality without being forced to
redesign their networks.
 
Cheers,
iLya
