The project is acively developed, you can have a look at its repository: https://github.com/onivim/oni2/

I think they are doing quite a good job, the editor is blazing fast and you can already use almost seamlessly many VScode plugins. It is clearly still a developer preview, with a number of rough edges, but the devs are very reactive on the issues and on the discord channel.

I bought it in the very early days to support the project. I still cannot use it as my main editor, but I have been using it more and more recently (I am using the nightly version).
