odd. after several repeated issues with amazon logistics (the worst was a package marked "out for delivery", then "business closed" for a full week of attempted deliveries - this was to a private residence up on a hill), I've only had packages shipped usps - it took several conversations with support staff, and after a few rounds of "free prime extensions", they stopped the shipments via amazon.

That's what it takes. IIRC, they'll only consider deprioritizing AMZL if you've had 3 misdeliveries (by their reckoning) in the last 6 months. I haven't had the time to basically go to war with them to get them to stop, I just shifted my shopping habits instead.
