RetoKummer SQL Server 2022 has nothing to do with it. SSRS 2022 was already released in March and SSAS was released this month, both before the release of SQL Server 2022.
The current SSIS extension in VS 2019 supports older SQL Server versions and so will the SSIS extension for VS 2022. No need to wait for a corresponding release of SQL Server.
Microsoft could at least release a SSIS extension that supports all current SQL Server versions and update the extension later when SS 2022 is released.
If they did this from the start with all of their own extensions then everyone could use the latest VS 2022. Microsoft doesn't even mention the lack of support for these extensions when you download VS 2022. And they made it also pretty hard to find the downloads of older versions of VS.
You may find the wait of a year acceptable, I don't and based on the many posts over the years about the delayed release of this extension, almost none of the SSIS users do.
