I'm not really sure who the target market for things like skidl and jitx is: people who think schematic capture is a laborious, tedious, and error-prone technique for entering data before you can get started on a layout, instead of a useful documentation step that will yield dividends over the lifecycle of your design?

The jitx folks used to talk a lot about making test jigs and adapters for people, which is a simple enough application that a text-based system could really shine at.
