[tripleo][ansible] the current action plugins use patterns are suboptimal?

There is a trend of writing action plugins, see [0], for simple things, like just calling a module in a loop. I'm not sure that is the direction TripleO should go. If ansible is inefficient in this sort of tasks without custom python code written, we should fix ansible. Otherwise, what is the ultimate goal of that trend? Is that having only action plugins in roles and playbooks? Please kindly asking the community to stop that, make a step back and reiterate with the taken approach. Thank you.
