DX

I found some users are trying to enable plugins which are not part of default preset, for example

{
  name: 'preset-default',
  params: {
    overrides: {
      cleanupListOfValues: true
    }
  }
}

To fix this I made docs more concrete about plugin (5165ccb)
and introduced a warning when true is specified in overrides (cb7e9be).
Please give us feedback if you still have issues.

Thanks to @IlyaSkriblovsky, @devongovett, @matheus1lva, @omgovich, @renatorib and @TrySound

Does any of this look wrong? Please let us know.
