I think this is all about trade off. I do agree with your point 1,2,3, rule-based is better in some cases, but it's not as expressive, sometimes you have to express the logic in a non-straightforward way to satisfy your need, when the logic get complicated. We're trying to make the system flexible from the backend, and improve the usability at the UX level. For example, the constants inside the language will go to a separate section in the UI and will have various components of tuning them. If the DSL code is organized well, it's going to look as clean as the rule based one.
