BTW, one more question: I still have a minor concern on the
assumptions that people can made on the order that files are included
in this feature.

Please, correct me if wrong, my understanding is at this stage there
is not guarantees in what order they would be loaded at all.

So I'm thinking that it would be good if we provide some good
default, ie. load them in alphanumeric order or similar.

That would be a follow up patch, but it would be good to sort out this
before nft 0.8 gets released.

Thanks!
