It may depend if you have something working already or not. Because you can build data flow before you started development. In some cases there are limitations of engine or framework that dictates you data pipelines. But also really valid point that should be taken in consideration. Thanks.

Yes. True. Thanks for you detailed comment. I thought about team composition also, whe I said that it won't be cheap. But your point is also highlighting development process dependincies. Thanks for that.
