Good news/TLDR
Yes, so far I have resumed from sleep 2x without any issues
with both of my workarounds disabled (kernel command line/systemd rfkill on sleep).
What I don't yet understand
This commit
(https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/diff/drivers/bluetooth/btusb.c?id=v6.12.8&id2=v6.12.7)
was a pure USB fix. My mt7922 device (not a USB dongle but built into the motherboard)
seems to be both a bluetooth device (bound to btusb driver) *and* a Wifi device (bound to mt7921e driver).
I remain puzzled as to how is it that the issue that is on the USB side was *also* fixed by
adding mt7921e.disable_aspm=y to the kernel command line (since that would act on the wifi/pci pathway)?
