Most other laptops don't even have the mode you need to put the ASUS in to get this bug.
I don't think I ever put any of my laptops into dGPU-only mode via MUX, it's stupidly power hungry with little upside.

Unless you specifically bought that model because you want low-latency output to an external display with G-SYNC.
I've used Asus motherboards in my gaming PCs for years, and their BIOS/UEFI firmwares there are equally awful, their Ryzen AGESA stuff has been a complete mess.
My G14 functioned just fine with G-Sync in Optimus mode via nVidia connected USB-C port (and didn't need reboot to switch between GPUs) so I never found real use for the MUX mode. It's telling that most other gaming laptops don't spend on that piece of hardware.
The switch solves a fundamental trade-off: an external port can only be physically connected to one GPU. If the dGPU you get GSYNC/etc but high power consumption if you connect an external display.
If the iGPU, then the dGPU is basically sending its frame buffer through the iGPU and is limited by it.

Not sure if this was in jest or not but I can say the same. Both when I daily drove a MacBook Pro, and when I was using a Razer laptop as a desktop replacement at the height of the GPU shortage (it DID NOT like charging the battery all the time, eventually it puffed up and I had to remove and recycle it, oops). Though I do see the utility of auto-switching for the average user, so I definitely won't complain about the existence of it. :)
I have. By specifically choosing an iGPU-only model so I wouldn't have to deal with all this multi-GPU nonsense. And AMD iGPUs are more than fast enough for light gaming which is the most I care to do on a laptop - just make sure it's a recent iGPU design in the GPU you get.
It sounded to me like they were multiple bugs. Some were specific the mux mode, but sleeping in an interrupt, and artificially re-arming it is problematic either way.
