yep , I also considering this for a while, then I think those ones are for cluster env settings, And this one is for application setting, which might not be need to be set for e.g. the example case. so I put it after the example to not over complicate the example usage. Say as a add on for advance usage. While I think you are right it's better to keep conf in one section, maybe we need a separate conf section to talk about all the confs?
