No, I mean in some previous mail Phil mentioned that it could break user's
script.
 I was thinking why one would use "nft export json" alone.
Earlier we didn't have nft import command.

So lets say if some user do "nft export json >file.json" then the
rules in file.json
are of no use without "nft import json" because we had no way to
import or use them again.

Sorry, I missed previous mail and couldn't follow up.


Thanks!
