BTW, I've created a pull request for nvme-cli
(https://github.com/linux-nvme/nvme-cli/pull/1237)
to add a new command-line option 'dump-config'; can you check if that's
what you had in mind or whether it needs to be improved further?

The dump is nice, thanks. I gave a couple of comments on the PR.
I do suspect that people will want to populate this file outside
of dump-config, hence we need a markdown documentation for it
or in this case a json schema...
