Hi,
A simple feature with a lot of potential value would be to support
passing nncp configuration on FD0 when the path is "-".
With that in place the configuration file can be outside nncp's
view of the file-system.
Also, the configuration could be piped through jq scripts that
attenuate the configuration by removing secret keys that would
be unnecessary for a given operation.
Cheers,
Emery
