This can be a separate effort. However, what I did not mention earlier is that we probably should disallow the creation of new out-of-region AUT-NUM objects if they are no longer required to authorise ROUTE(6) objects.
how long do you think it will be before there are no inter-region barriers to AS transfers? add a year or so to that to give people time to clean up the mess caused by this policy hole.
It is not entirely clear to me what the issue of inter-RIR ASN transfers has to do with the topic at hand. However, there is a lively discussion on ARIN PPML about Inter-RIR ASN transfers, you too can participate: http://lists.arin.net/pipermail/arin-ppml/2018-February/thread.html
there is a lively bunch of animals in that pile of chicken manure over in the barnyard; you too can participate. i'll count my chickens when they hatch. in the meantime, i have ARIN ASs announcing RIPE prefixes, as do many others. randy
