The intention of the trap is letting you know the current status
of resources (such as running/stopped/etc.), and not the result
of each operations. This is similar to LHAResourceGroupStatus
object which is the resource status V1.
(The note above is just for an explanation that how it's implemented.)

But, yeah, your point is right and it might be also useful.
Does anybody want to use this information?

We're considering to extend it more, but before we proceed
I would like to design the new MIB definition first.
Does anyone have comments for this?

I would like to hear more, particularly about what kind of
information is needed from whom really wants to use the SNMP agent.
