@gfanton , these changes seem harmless, but are they being used anywhere?

[jefft0]

@jefft0 to do a local replace and see if we can still compile dependant repos like weshnet and berty. Check if the changes in this PR force those repos to implement json marshalling.

[jefft0]

I did a force push of of rebasing this PR to the latest master.

[jefft0]

This repo is a dependency for go-orbit-db. I update its go.mod with a replace to use this PR. make test on go-orbit-db has a stack overflow error. See the attached log.
error.txt

@gfanton said "Looks like a recursive json unmarshal. Will be hard to find".

[jefft0]

I confirm that we can build go-orbit-db, weshnet and berty with a local go.mod replace for this PR. But still have the "stack overflow" error shown above.

[jefft0]

@gfanton will ask if it's OK to merge this.

[jefft0]

Closing. @gfanton says "doesn't think it will be useful anyways and can probably introduce some problems."
