 We recommend checking out [the updates we've made to the addon-kit](https://github.com/storybookjs/addon-kit/pull/60/files#diff-8fed899bdbc24789a7bb4973574e624ed6207c6ce572338bc3c3e117672b2a20), that can serve as a base for the changes you can do in your own addon. These changes are not necessary for your addon to keep working, but they will remove the need for your users to unnecessary install `react` and `react-dom` to their projects, and they'll significantly reduce the install size of your addon.
 These changes should not be breaking for your users, unless you support Storybook pre-v7.
