I really like the idea of Deno and Fresh's philosophy also resonates with me (I'm a Rails guy). I would like to see an integrated ORM (can be an existing one) and testing framework though, before I would consider it a "full-stack" web framework.
1. first class styling plugins
2. synchronized island state
3. built in data persistence
But yes, I guess if I would need to pick a more mature framework with JS, Redwood would be the way to go.
