It took me less than a day to start to be productive on my fork [0] for what i wanted to do. The default spacial units are actually microns (but yes they have their[1] examples multiplied by the inch conversion) and the wavelength stuff is in meters. But yes, technically its v0.0.1 so still rough around the edges.
Considering the vast majority of money in the space going into QEC software, I'm so grateful for their work. Was so much easier than trying to everything from scratch with my limited CAD work over the years.
