The integrated GPU isn't the problem. The MBP only uses the dGPU for external monitors. The problem is that the dGPU driver/firmware/whatever is broken so it runs at a minimum of 8W even when there's no work to do, overloading the thermals. The 2019 16" MPB made this problem far worse, raising the minimum dGPU to 18W, making external displays almost completely unusable for more than 1hr at a time unless you put the laptop aside in an external cooling solution (stand and fans) where you can't ergonomically use the integrated keyboard.

That makes me glad I figured things out, and got the eGPU, because I was really close to buying a newer model in hopes that it would fix things. I really don't understand how this isn't more of an issue for Apple. Surely theres a lot of pros out there using external monitors. Two external monitors is pretty standard - in my previous life as an IT guy we set that up for probably half of our clients.
