Man what is even the point of GitHub creating its own entire CI framework where the whole selling point is "you can encapsulate reusable CI logic using dedicated Git repos" when they don't even maintain their own first-party packages.
This issue has been open for more than half the lifetime of GitHub actions, asking for a clearly missing piece of functionality in actions/checkout, the most basic first-party utility action. Now, as an open-source maintainer myself, I'm sympathetic to the difficulty of keeping up with even reasonable feature requests. But there's also been a pull request implementing this behavior open for nearly as long, with zero response from maintainers.
Why go to the trouble of creating this system only to abandon it?
