To me there is a drawback of becoming to much of a DSL (internal or external) in that it requires a lot of new learning (imho internal DSLs are easier to pick-up since they take advantage of the surrounding languages capabilities, in this case python). So that’s what I just want to keep in our minds that we need to make it simple *enough*, or we will die a nasty death of complexity :-P
