The TC default block is there because the indirect registration may happen _after_ the block is installed and populated. It's the device driver that usually does the indirect registration, the tunnel device and its rules may already be set when device driver is loaded or reloaded. I don't know the nft code, but it seems unlikely it wouldn't have the same problem/need.. Please explain.
