I guess this is the same or similar idea as #14336? It helps if you can explain a bit about what the implementation looks like. I guess you know it's already possible to some extent .

The PR looks interesting, but I'd like to see a proposal that also accommodates annotations (if even not implemented right now, it would be nice to figure out the design first). I don't know if it might be worth trying to be able to use expressions and aggregates directly in list_display . In any case, I'd like to see a discussion on the DevelopersMailingList to get a consensus on the design.

Can't get enough traction in the mailing list: https://groups.google.com/forum/#!topic/django-developers/T1-80RV8b5g

Tim, perhaps you could help by chiming in?
