I think we should also update :

• push-release.yml
• storybook.yml
• pr-clean-storybook.yml
• push.yml
• next.yml

Or at least, clean those to not use the strategy?

I've taken the approach of updating the other workflows to use node 16 and only having the PR workflow use the matrix.

This gives us confidence that changes made will build on node 12, 14, and 16 while only building deployable packages for NPM or storybook using the latest version.
