This is a wish from the Reparatursommer board.
The user script veAutocorrect is a helpful tool used in VE.
But it is currently not included in the reduced VE that is used in the new discussion tool. Let's change that!
Adding the user script to the discussion tool would be possible by using a hook. There is already a discussion happening about API hooks or different ways of accessing the toolbar: T265981: Provide an API to hook into new reply editor.
