I have mine with the original stand from JBJ. And it’s fire sure not made to over hang like that. I would not leave it like that. If anything, cut a finish ply to the size of the tank then laminate it on the edges in the color you need it to match.
im with isaac here, it would definitely bother me. reminds me of the floating panel red sea tanks.
i didnt use the included pad and bought a larger one with a sticky side and cut it directly to fit the entire jbj stand top on my jbj rimless 25
