There are cool things somewhere in the middle now too, e.g Cue [1], which is really cool. I was recently thinking that its a shame there isn't a cross language proto-lite kind of thing (I'd settle for json with structures and pointers) that has a great devx. The multi step transform that configs are right now (from the serialization representation to the code one) could be eliminated. IMO interop is one the most important things for configs, so I'd be hesitant to use a thing that needs a preinstalled runtime. [1] https://cuelang.org/ https://cuelang.org/
