I, for one, need to gain operational experience about RPKI, and start to
form some BCP's that will be helpful in the coming months/years.
RPKI is here (like IPv6 and DNSSEC), so the time to argue its merits is
long gone. One is welcome not to use it if they so wish, but for those
that want to, we can only gain experience when the base system is stable
and free of simple, reasonably avoidable errors.
