Why is it that 1.16 behavior folder works instead of the normal behavior?

You guys should create a simple script in which you can link your player to the console. So that you can fix ban issues. I am saying the xuid. Mind if i work for you guys? I have probably the best server you can think of with your helpfulness. I just dont have a computer to run it yet and i was thinking if i can be one of the main servers. I know a bit of c++ where i have created simple ai's so far. My main goal for c++ is to create an AI upscaler but i have 0 ideas how to do that. I am because otherwise my big profit project to partner with you will cost me thousands if I partner with "this company". About 9 cents an image but I'm looking to get that electric cost cheaper with just my laptop. Because i want to upscale everything and create the most vannila like texturepack in history. I could of sent you the 4096x4096 panoramas which is twice as much pixels as 4k in a single image. Also please make it so that everything is in the behaviorpack file and the delete 1.15 and lower with 1.16 being the copied folder.
