I think OpenSCAD neatly demonstrates the issue with 3D modeling: when you come from a tool like Blender it might look amazing that you can now trivially change dimensions mid-design, but what you're really looking for is the parametric modeling you get from something like Solidworks.

Schematics-as-code doesn't solve a problem I am having. What I want, is for an easy way to import "snippets" in KiCad: I want a library where I can select an MCU, and it'll automatically add all its auxiliary parts too and let me choose from a few pre-made standard routing options. Maybe even make it parametric so it becomes a nice little wizard where if I'm adding an LDO I can enter a voltage and it'll calculate the adjustment resistors for me.
