Vue3-migration-helper: when is it foreseen to be available?

Clicking on the homepage and on the repository links, I get “page not found”
Actually the npm page says: “It’s a placeholder package for now”.

Since I need to use react-like context as described in this example:
https://markus.oberlehner.net/blog/context-and-provider-pattern-with-the-vue-3-composition-api/

I would like to know when the migration helper from vue 2 to vue 3 will be provided.
