Let's do the same thing we did for io_uring queues? An empty nest:
https://lore.kernel.org/all/20250116231704.2402455-6-dw@xxxxxxxxxxx/

At the protocol level nest is both smaller and more flexible.
It's just 4B with zero length and a "this is a nest" flag.
We can add attributes to it as we think of things to express.
