Mostly empty, often outdated, and could be merged into Maintainers anyway.
Opinions? Maybe @JBranaa (WMF)?
Topic on Talk:Developers/Maintainers
I'm of two minds about it. It is a historical status for people who are working with stewards/maintainers to be able to take on the work in the future.
But, in reality, if that's happening, that training is most likely a fluid activity and hopefully temporary (with someone either becoming a part of the stewardship group or not). So... as I've typed this out I think I agree that the information gain is minimal.
But I'd still like @JBranaa (WMF)to provide his feedback as he's the owner here and I'm basically over-stepping his work ;)
