Somehow I missed this a few years ago, and I bet a lot of y’all did too. Note the new “Recommended” column in the memory settings documentation:
These recommendations are also set by the SQL Server 2022 setup wizard if you choose the recommended settings on the memory step.
The documentation change was made in this pull request, and I don’t see a Github issue or documentation/comments around the recommendation, which is totally fine. I don’t expect (or desire) Microsoft to have a public discussion on every settings change they make – nobody would ever get anything done, hahaha.
