Q:

Partner object - workbench says it's triggerable - but it's not

I need to create a trigger on the OpportunityPartner object. I know it's not triggerable.
However, looking with workbench on the 'Partner' object, it's triggerable attribute is 'True'
Is that a mistake?
I still can't have a trigger on the 'Partner' object either.

A:

I talked to the team that owns the Partner SObject definition and they confirmed that it does not support Apex triggers. 
I've logged a bug internally (W-5266695) for them to investigate correcting the erroneous describe information.
