That is awesome news! I've been playing with 10up's actions for a while, but I couldn't make it work. I am currently trying to work my way through the errors, and it seems I need a `package.json` file, just like the new block plugins.

If it works, I have around 10 overdue plugins to update. I do this remotely a lot from various places, so I don't need to be tied to a specific software. Being able to update everything from GitHub is a godsend.
