I was thinking the same and this reminds me of the various strategies implemented in packet fanout. tun_cpu_select_queue is analogous to fanout_demux_cpu though it is tun-specific in that it requires tun->numqueues.
Fanout accrued various strategies until it gained an eBPF variant. Just supporting BPF is probably sufficient here, too.
