It's good to see a status update for Vue 3, and creatively done I must say. If Vue's (Vuex) TypeScript support wasn't as bad as it is in Vue 2, I would not be as eagerly awaiting this 3.0 release. Currently on the fence to rewrite a large project to Next.js + TypeScript + Mobx as I have to move things forward and expect the whole ecosystem to take a long time to catch up.
