Any chance you can put a setting into your mod that swaps pathing to be free? I made a compatibility mod a while back for this, and I just wondered if you might end up integrating it into yours. One less mod requirement for people if so. I haven't done Factorio modding in ages, so I figured I'd ask you first if you were willing to integrate this into your mod before I try and update mine.
Mine, for reference; https://mods.factorio.com/mod/freelogicartpathing
