As much as it is a good idea, you should see my mod without the atmo... It looks really nothing like it x) just floating stuff... Now Imagine a mod with loads of background objects without it

I'd like to add that I recently was working on a new parkour mod that would have the players follow a certain path in a huge environment that's basically copy pastes (basically this).

I could've had those unused platforms be background objects, and solely made my path with the physical ones. Instead, I had to make one simple path. (And even then I lacked objects to make it as pretty as I wanted it to be ><)
