We can't do any of them in scope of this PR and this feature since it is a breaking change.

@alepauly is it ok for you if we make the changes outside of this PR?

I don't think that we want to do these changes in near future.
Java size is pretty small and removing Java 12 won't give significant win.
But impact could be pretty huge, especially from switching default version

We can discuss/do it as separate work. The main reason of getting rid of Java 12 is that it sets the expectation that those intermediate versions will be available. I rather have setup-java and useJava deal with that. Once those download on demand we should be able to remove any version (communicating prior that Actions/Task is recommended method).

We'll eventually have to switch to Java 11 as default but I'm not sure the time is right. Perhaps we can see version usage through setup-java/useJava and that will tell us when we should.
