The reason to have the bottom floating is that silicone is far superior in tension than it is in shear. A small nick in a seam, can fail catastrophically if it's not in tension.
That being said, I have a 20"Wide x 20"Tall x 7" Thick that is sitting on the bottom pane of glass for over 3 years without any issues.
