Hi,
I would like to work on this issue.
I have one question for a start, is this a matter of adding support for the --logging-format=json flag? (similar to this PR)

Are we trying to have a structured logging mode?

I believe this is what is this issue is asking for.
I am new here, is this something aligned with the vision of the project? Can I work on it?

Thanks for your work !
I will be happy to test it soon
