Authorship as a strategy for news SEO is all about leveraging your writer’s E.E.A.T. and communicating topical authority.
We've recently implemented schema on our author profiles. It's very basic since our author profiles don't contain that much information but perhaps others in the same situation will find it useful.
It's better to have proper schema on even a little bit of information than nothing at all.
