That's right. It's an INSPECTION only item at all 30k intervals. It is suggested for replacement at 100k per the service manual.
FACTORY RECOMMENDED Service for 100K Miles /120Months

I don't disagree with your recommendations, but what you wrote may be confusing to some. There is a serpentine belt(accessory belt) and there is a timing belt(drive belt). There is no such thing as a serpentine timing belt.
The reason people do water pump at the same time as timing belt service is because you have to remove a ton of stuff to get to the timing belt - and water pump life is typically about the same as the timing belt and relatively cheap in parts cost. As you stated, the GS has a timing chain, so you can wait until signs of leak, and when it does, do yourself a favor and get the thermostat and tensioner done at the same time while you have the coolant out.

My 2003 Tundra 4.7 had a very serpentine timing belt.
