Fuel tank under tray

[3yearplan]

Is the plastic tray under the fuel tank really necessary? What is the real purpose? I would guess it is to avoid abrasion of the metal tank straps against the metal tank. Does everyone use the plastic tray ?

It provides lots of impact protection from things you might run over. I kept mine.

As well as does not allow metal to metal wear (or sparks) from strap to tank. And it looks prettier ;)
