CAD system must be reliable. It is simply unacceptable to have math issues which cause unpredictable geometries.
CAD system should have a good UI. This is a big issue for open source software in general as UI and UX is usually an afterthought.
CAD system should be fast and use hardware acceleration. Running single threaded python scripts on CPU to do complex computations kills the productivity. Designing real life objects is already a mentally taxing task, the whole purpose of CAD is to remove the computational bottleneck of a human.
CAD should be object aware. If I draw two gears and put them next to each other, I should be able to rotate one and see the other moving accordingly.
This is a bare minimum, I'm not even talking about computational modelling, stress testing, etc.
