I didn't get the M1, that's why all the extra stats in my model. I needed the dedicated graphics and large screen of the 16inch as well as windows capabilities. I'm not sure if you also didn't get the M1, but it sounds like you did, that's definitely a contributing factor. I think the 1TB 16GB m1 mbp have been the most constrained models getting out along with the 2tb.
That being said based on your order time I would've thought you'd see movement by now, but considering the date you got so early on November 10th it sounds like it was constrained even when you checked out. Still I know the horror of endless processing, and 16 days is a long time to wait. December 3rd is about a week away and aside from Shanghai gang I haven't seen any late arrivals yet. I'm hoping for you that you see movement soon.
