Change default boot set

[NullVoxPopuli]

In the wake of #564 and the complexity introduced by: #566:

This PR inverts the default (intended bug fix, due to the bugs introduced by #553)

For folks that need the early boot set, you'll need to opt in.

The earlyBootSet is still a function, and still receives the default recommended values:

autoImport: {
  earlyBootSet(defaults) {
    return [...defaults];
  }
}

@ef4 the tests that work with the earlyBootSet set the option manually. All existing tests are passing -- lemme know if you think more is needed

Thanks a lot.
