Would it make sense from your side to to declare ABIv2 stable? It sounds to me like you break the ABI between FreeBSD 13 and 14, right? That would remove the problem of differing versions between upstream and the system version. No guarantees that we actually do this, but I would be in favour of setting such a precedent. (And we would probably need a few months to get everything going.)
