It was discussed on the meeting held today. It was agreed to report for
specific internal action such as VM migration, Host fencing,... but not
for the event itself (in order to prevent from flooding the Tasks view
from frequent events).
I think SPM election/status is an interesting enough task that if it
happens it should be documented (as well as its process/results).

No. The Step is created in adjust to the execution unit it describes. In
order to prevent from additional update, it should be created with
status Started and start time.
oh - I thought a job is pre-defined with its steps, then the backend
runs them.
from your reply i understand the job/steps are just documentation of
what already happened?
