Has anyone has seen anything like 0.8%/hour in the wild?

Yes, see:

[TRACKING] High Battery Drain During Suspend

Small update after being in a situation where I’m actually relying on the battery quite a bit. The nvme.noacpi=1 option indeed makes a huge difference. With Fedora 35, Linux 5.17.4-200.fc35.x86_64 I’m now seeing: s2idle with HDMI and USB-A inserted: 1W s2idle with just USB-C cards inserted: 0.34W “idle” use (reading something on the screen, with rather low screen brightness): about 4W “screen locked” use (screen off): around 2W So I’d say the nvme.noacpi=1 has almost completely resolved…

That is with an 11th gen i7, 16Gb, and (most importantly!) all USB-C.
