> It made me wonder if anyone has considered making a complete list of assumptions that are baked into these models, so they can be looked at in detail.

Yes, they did, it's called an "ensemble model" when multiple models are collated to account for their different modelings.

A friend of mine did his physics PhD on cloud formation at a molecular level exactly to tackle the issue some models had to account for that over longer time scales, most of the holes you can think of from the top of your head have been considered, there are many thousands of very smart people working on these models for the past 30-40 years.
