I'm trying to make the argument to migrate to SharePoint 2019 within my company. The company consists of over 50,000 internal employees and 25,000+ external users. Both PowerPivot and SSRS Integrated aren't being supported in a SharePoint 2019/SQL 2016 architecture. However, both are still supported in a SharePoint 2016/SQL 2016 architecture. Microsoft has already announced that SQL 2016 will be the last version to support both features. Microsoft, how about you also include support for both features as long as we use SQL 2016. :)
