Per this React Router announcement, React Router and Reach Router are now the same project (more or less). The Reach Router docs says
Router manages the focus of your app on route transitions. There’s nothing you have to do about it, it just happens.
At present there's nothing in the React Router Web API docs about focus (I did a text search) and the roadmap has
Add focus management APIs
in the backlog.
Is this feature still coming or are we waiting for this React RFC or is it there and not documented? Asking because it's been a while since the announcement and it's understandable if there are documentation gaps. Want to make sure it's really not there before I keep rolling my own.
