Description

There seem to be some requests for making the operator (non-keyed) state queryable. This means that the user will specify the uuid of the operator and the taskId, and he will be able to access the state that corresponds to that operator and for that specific task.

This issue will serve to document the discussion on the topic, so that everybody can participate.

I also link till.rohrmann and skonto as he also mentioned that this feature could be helpful.
