Add to this:
- Is it possible to correctly identify the hardware platform, so that we know
where to find the sensors and know what they measure, without bloating the
kernel with a lot of tables.
The major technical challenge is that sensors are not documented on the majority
of systems, unless you know in advance where to look for them.
IPMI and ACPI tries to do something here, but the former is only available on
serverhardware and the latter more often than not, comes only with the minimum
necessary to avoid melted plastic.

Never attribute to malice what can adequately be explained by incompetence.
