World Space UV shader

What if we had a option in the lit shader that used world space UVs instead of Object UVs that are set. Lets say i made a combination of buildings in one. instead of making a probuilder shape, making the model, and having to match up UVs so i dont get a seam or stretching, i could just make a building out of a basic cube and the tiling is done for me. this could also eliminate the Z Fighting that could happen.
