I've had our application admin team create an 'Involved Groups' multi-select on each template, which is mandatory to fill out, so that teams involved with that article are listed.  The purpose behind this would be to export or search on a knowledge domain for a particular group, so they can review knowledge articles applicable to them and see what articles they're using most frequently.

Definitely an up-vote from me:  It'd be great if there was a standard way to do this in the Knowledge Article without having to manually modify anything.

Also add stakeholders as a search criteria across all relevant search pages
