I can just rework userspace to allow going via xt_bpf but its brain damaged. This helps gradually moving towards move epbf for those that still heavily rely on the classic forwarding path. If you are open to BPF_PROG_TYPE_NETFILTER I can go that route as well, raw bpf program attachment via NF_HOOK and the bpf dispatcher, but it will take significantly longer to get there. It involves reviving https://lore.kernel.org/netfilter-devel/20211014121046.29329-1-fw@xxxxxxxxx/ as a first stage/merge goal.
