I can give you my rimmed 37g (raised bottom glass panel) setup as an example. My stand (a heavy duty cabinet) has raised 1x4 trim on either end which the tank ends rest on. In order to support the front and back panels of the tank I put 1x2 trim wood from end to end to fill this gap. The entire bottom area of the tank has no fill what so ever, it has been setup for over a year with no issues. Total est. weight of my DT is 350lbs.
IME/O, as long as the rimmed bottom of the tank is supported and level, you're going to be just fine.
Rimless tanks DO need full bottom support. The panel isn't designed to be self supporting.
