I think this is the idea of these `JDK_SUBMIT_FILTER` and `JDK_SUBMIT_PLATFORMS`:

https://github.com/openjdk/jdk/blob/4a6cbe47daae82970c36c8cd86655581b2c59f59/.github/workflows/main.yml#L86-L92

Admittedly with my current setup this wouldn't work for Alpine. The only other option I could think of is maintaining a list of "skip unless explicitly defined" platforms in the `check_platform()` function. I'd be happy to put a prototype together if you'd prefer this solution
