I think we should tweak this such that we add multiple buffers but only make them visible to host after all add commands were successful. With split this is possible by deffering avail idx update, with packed by deferring update of the avail bit in the descriptor. I'll write a patch to add an API like that to virtio, then we can switch to that.
That's great ! Looking forward to seeing that API.
