Maybe they could integrate the Solvespace constraint solver. It seems to be gaining popularity outside its original CAD program.

I tried to use Solvespace for a number of projects, but it seemed like it had essentially ~zero support for parametric repetition (e.g. putting one hole every 15mm), which made it basically useless for any semi-complex project. A home might be easier, as long as you don't have any design features like "put a light socket every 3 feet".
