Managed Instance of SSRS would be great
A Managed Instance of SSRS to report from a SQL Managed Instance would be ideal. The requirement of having a local (or Azure VM) SSRS server to report against a SQL Managed Instance kind of defeats the purpose of "managed" for those of us who need to generate reports. Power BI does not cut it for the types of reports SSRS can generate.
We definitely need a version of SSRS that runs in Azure.
When companies make policies for target operating environments as PaaS preferred and SQL Managed Instance is supposed to resemble as close as conventional IaaS server, missing SSRS makes it challenging though might have some workarounds. It makes sense to have such services also made available for configuration.
