In that case, a provider selecting this implementation would need to make it clear to customers if they would be billed for a WaitCondition resource. I'd prefer to avoid this scenario though (regardless of the plug-point).

I don't think its wise of us to make decisions based on what a theoretical operator may theoretically do. If the same theoretical provider were to also charge users to create a trust, would we then be concerned about that implementation as well? What if said provider decides charges the user per resource in a stack regardless of what they are? Having Heat own the container(s) as suggested above doesn't preclude that operator from charging the stack owner for those either.

The way I read it Randall was not saying that the question was silly, he 
was acknowledging that his own examples (like charging per-resource) 
were contrived (to the point of absurdity) to illustrate his argument.
