hpdiags and hp-snmp-agents both use this driver to gather basic
management processor info, stuff like MP NIC config and stats,
serial number, etc (but no sensors).

I know of no plans to use this elsewhere.

HPSMH is "System Management Homepage", and SIM is
"Systems Insight Manager".  They both are web based management
consoles, and show the info gathered by hp-snmp-agents and hpdiags,
along with lots of other system info.

That is true.  Even if there was a management processor framework,
I would still want a simple read/write interface, to support
our existing software.

It isn't needed/used for sensor info.
