this is a really awesome improvement - a bunch of my projects all deploy w/ actions using the same api token to cloudflare workers (using wrangler-action[1]), so this makes it super easy to add new projects or re-roll the key without having to go in and change each project's config.
btw, if you're looking for an intro to github actions, i put out a video last december covering publishing your first github action workflow: https://youtu.be/J4EhgEskSZA
