Yeah, i get this and would say its ok (basically discussion vs LTS or latest in examples / getting started). But 2.0.0 is experimental, so i would not promote that in getting started etc. for now?

[sbernauer]

No strong opinion. On the other hand no one is probably testing 2.0.0 otherwise ^^
Just FYI you updated examples/simple-nifi-cluster.yaml
