Leaving aside the naming debate, and the debate about what kinds of
sensors and status info qualifies as "environmental", from a purely
mechanical view how would the implementation of a framework to report
non-environmental sensors and status differ from what we have now as
envsys?  Do you see a technical issue with fitness-for-purpose, or a
problem with fit-to-intentions (regardless of how the latter might be
resolved)?

Either way, where disks are reporting temperatures and other status,
and especially where ses(4) and similar facilities exist, having clear
connectivity between physical attributes (inlcuding fault LEDs) and
software constructs like RAID status is incredibly helpful.  Whatever
the underlying mechanisms, clear linkage for users and admins helps
avoid all sorts of errors, like pulling the wrong disk when trying to
repair a raid fault.
