Outlines like in the Measureit Arch add-on

Blender line art options are always so heavy for the PC to run. I was using this Measureit Arch add-on and I noticed that it has a line art option and it's very fast. While blender has only freestyle or the recently added grease pencil line art, both kind of heavy. There's also this npr render called Malt, but it is a whole other render engine, and not super fast either. I'd like blender to create a line option like the one they use to outline objects when selected, or as the outline option it already has for the viewport, but an expanded version, with more options beyond activating and deactivating.
