I believe that the warning messages in Revit should be edited to include a severity level such as (Minor, Major, Severe) to every single one of the warnings which show up. This way if there are hundreds (I know we should keep it clean but no one ever does), BIM Managers & Users can quickly process the most concerning ones first to quickly improve model performance and stability.
I also believe that there should be a color background coded for these severity levels and applied to the warnings dialog so its further brings user's attention to the warning severity level.
To go the extra mile, I think that warnings should be tracked against the username of the creator so we can quickly assist with training better practices for these users.
