You can think what you want, but it's a gimmick, and you have bought into it lock, stock, and barrel as most in the hobby have.
How long ago was that bagged up? How long has it sat on a shelf waiting to be bought? How long did it sit in a warehouse waiting to be shipped to the LFS(or amazon in your case) to be sold? Think if it was shipped on a UPS truck to your LFS in the winter it didn't freeze, or get super high heat in the summer? After all that, how much bacteria do you think is still alive?
Still think it's not a gimmick?
I digress though, and this thread is not the place to discuss this.
