[Karunamon]

I notice none of these problems on a 3.2 deployment with about 500 nodes.

I find that Ansible is roughly identical doing the same things on the same machines timewise, not going to get into the subjective argument about the language, the parser syntax is backwards compatible between major releases (and they go well out of their way to warn you what you'll need to change before something actually does break), and I don't see how it's any harder to test locally than any other config management tool.
