Paracelsin adds a machine called the "Mechanical Plant" for crafting things like inserters, rails, engines, etc with a +50% productivity bonus. I'd love it if the Quality Processing components which are currently limited to standard Assembly Machines (post processing kit, calibration matrix, etc.) could have their recipes enabled on the Mechanical Plant if Paracelsin is installed.
This wouldn't risk imbalancing early-game resource demands at all, since accessing Paracelsin is parallel to Aquilo in terms of progression.
I hope you consider it!
