Sure, but I won't self host something, and basically contribute as a tester, without knowing what it will look like. This is due to how I value my time.
Self-host might not be the right way to think about it. It's more of a video game with a built-in web server, like Age of Empires where one player hosts the game for everyone else.
The only difference is all the other players only need a web browser to connect. But you can play the game from a single computer if you want.
