There are a few of these sorts of things already. I'm not really talking about opinionated frameworks (or collections of various github projects stuff into a big meta project). https://reactjs.org/community/starter-kits.html
What I'm talking about is something more akin to this statement:
https://angular.io/guide/forms-overview "Handling user input with forms is the cornerstone of many common applications"
But isn't that something React wants to avoid? I remember reading somewhere that React does not want to recommend any approach to forms, routing, etc., but leave it to the user.
