Can you elaborate on this? What's the ping-pong problem?

Is it permissible, from a policy perspective, for a multi-homed end user
to announce the numbering resource allocation received from one RIR (for
discussion purposes, let's say ARIN) to upstream service providers in a
different region (for example, in the RIPE region)?
Is it feasible from a

I don't think anyone is suggesting that you should put NAPT in an IPv6

blocker to moving to IPv6 was the lack of NAPT, and the security
