The devs should just me "no build restrictions" a default thing or at least an option in the settings.

I'm not a dev, and I try to get devs a lot of grace and benefit of the doubt for why certain mechanics are not implemented or why certain things programmed they way they are.

That said, with mods that already do it, why do we need build restrictions in the game - with the bare amount of base material to build with, the build restrictions just make what is already the bare minimum feel even more scarce and hardly capable of allowing any real creative layouts.
