Different needs for different domains. For example, there's an old pack of machine learning code that I maintain, and it (and a bunch of other Java code that I see from other institutions) does not use or need DI, ORM, Auth nor proper REST, they typically handle processing of non-database data with no or minimal web interaction, and plain old objects are fine for that - if we started from scratch and chose Java instead of some other language, we would still not use Spring for that.
