IIRC we added it in the rx path, mainily for loopback to pass the 
ownership from the tx socket to the rx socket, but here we are already 
in the rx path, so the skb will never leave this socket.

Maybe it's necessary for the eBPF path?

In any case, I can add it, but if you can help me better understand what 
it prevents, that will also help me add a comment above it.

Thanks,
Stefano
