The cloud formations serve as *examples* to setup user provisioned infrastructure. There is no expectation of it adhering to installer provisioned infrastructure standards.

Comment 2 Johnny Liu 2019-04-10 01:34:24 UTC
From customer view, user would start his/her 1st upi setup using these *examples*, why not make these *example* more thoughtful. And I think this fix is not hard, still suggest to fix it.
