Framed aquarium and rubber mat

[Fishess]

Hello so i built a plywood stand (Really strong, it has 6 (7 legs if u count back panel) of 0.7 inches (1.8Cm) plywood..
Here's my question:
Lets say after leveling surface of the stand, so it's all level and even..(As much as i can)
There are 0.05 inches (~2mm) small bumps or imperfections on stand surface.
Is it worth ussing rubber mat under framed, rimmed aquarium? To level all the imperfections out?
(Or to be extra safe from aquarium cracking)
Under the tank it self, there will be thin plywood, then the rubber (standart aquarium mat)..
The aquarium is juwel lido 120 <<<<

All the weight of a rimmed aquarium is carried by the frame.
If the imperfections do NOT touch the glass of the tank, then there is no reason for the mat. If they do, then they have to be leveled/removed somehow. There glass should NOT touch the stand.
