I would turn this around… I don't believe anyone has presented
a strong argument for allowing ASN transfers and I do not believe
that the community would benefit from such an action.

I'm not completely sure the transition to 4-Byte ASNs is actually going any more smoothly than the transition from IPv4 to IPv6 and there may be similar argument to allow the transfer to 2-Byte ASNs as for IPv4.
