lm-sensors wont work with external USB drives as it only knows about
things connected to the internal busses of a machine such as acpi and
i2c, and the Pi only had the latter.

 No. See for example here:
https://www.kernel.org/doc/html/latest/hwmon/drivetemp.html, the
drivetemp driver uses ATA commands to read temperatures from drives or
alternatively, using SMART attributes. lm-sensors either uses the
drivetemp kernel driver or just reads from /sys/class/hwmon.
 

I checked and drivetemp module is invoked in the kernel.
# zgrep -i temp /boot/config-6.12.25+rpt-rpi-2712
# CONFIG_SYSTEMPORT is not set
CONFIG_SENSORS_DRIVETEMP=m
# Temperature sensors
# end of Temperature sensors
But I have no idea how to access anything with it.

Which is why I said before, I find it odd if smartctl works and
drivetemp does not, although AFAiK no one has actually tried that in
this thread.
 

How does one 'use' drivetemp?

Unfortunately I don't have any recent USB HDs around. I do have an
USB-SSD case but don't have a spare SSD to put into it right now.

PiOS is always a little bit 'a road less debugged' than *x86...especially in terms of stuff that accesses hardware.
It reminds me of mainstream Linux 10 years ago. And hacking UDEV to get it to recognise a camera.
