Currently there's not yet a node config and the WA config is
somewhat "tightly coupled" to the user entries in that
changing it can lock them all out, so for now I opted for
fewer reorganization and just use a digest of the
canonicalized config here, and keep it all in the tfa.json
file.

Experimentally using the flatten feature on the methods with
an`Updater` struct similar to what the api macro is supposed
to be able to derive on its own in the future.
