See through able Portal And Non Euclidean

There is a java mod for this, but what if it was a main feature? I think it would be a great feature for minecraft, for both java, bedrock, and all devices! People could make amazing builds, like an impossible house! I think people would really like this feature if they are into non euclidean things. How it would work - There would be a button that is See through able portals and if you clicked it then it would activate it, or the button would be in the area where you make your world. Again, I think this a great feature for the future of all versions of minecraft, bedrock, devices, or java. Thanks for reading this!
