Here is another programmable CAD project, Fornjot[1], also in Rust. Fornjot, too, is being actively developed.

Unfortunately it uses Rust for model description (compile times/learning curve).

That said, one could probably easily put a layer of scipting lang in-between. E.g. Rhai[2] or Lua or whatever.

And I guess if their tech is solid enough, someone will do that eventually and open a PR or fork the project. They do not use an existing geomtry kernel but do everything from scratch which makes this a very interesting endeavour.

There also seems to be a goal overlap between Fornjot and DieselCAD
