Make businessKey available when getting task list?

Would it be possible to enhance the /task REST API endpoint so that it returns the businessKey of each result? Each processInstanceId is returned, but in order to get the businessKey (to correlate the results with data in another database), we need to make an additional API call to get the businessKey of each process instance. If we’re processing a large set of results from the /task API endpoint, this can be very inefficient.


I agree this one above would be nice to have.
In the mean time this could be workaround BusinessKey didnt show in History API (both, Rest and Java), but shows in Cockpit
