I'm also a plat member, and I would also ask "is it sooo important" ?
I never check upper room availability, I never expect upgrades. So, 3/4 of the times, I get a good surprise at check-in.
I scarcely use the drink voucher. I never touch the fruit basket. I only require a big bottle of water at reservation stage and it is indeed always prepared as a complimentary gesture. And quite often, I get extras without asking. Last time was a box of macarons.
Of course, I have my way, you have your way.
For your reference, I spend 70/80 nights per year.
