<pre>Hi Anthony,

Technically when we were exporting json by "nft export json" it was giving us
low level virtual-machine(vm) pseudo code. So we renamed it as "vm json".
As you have already mentioned that you are able achieve old behaviour by
"nft export vm json", that is right behaviour.
Further, by this renaming it creates scope for high level json which
represents abstract syntax tree of nft grammar. This high level json
can be exported by "nft export json".
But this feature is yet to come in mainline so we are doing "no operation" we
user executes "nft export json" and it returns 0.

I hope above explanation clarifies this.
I'm cc'ing Phil, he may put some light on high level json.</pre>
