The person you're responding to has done some great work on the fundamental CAD stuff, moving some functions to use eigan for significant performance increases. They seem to me like they've got a pretty solid grasp of the underlying CAD kernel. I think it would be great if some other people were able to step up and help modernizing other parts of it, making distribution easier, that kind of stuff. I think phkahler has the skills to revive solvespace, but there needs to be some other core contributors who can help out with the build, UI, on-disk format, and the like.
