I use Xcode (and its predecessors since '90) I ALWAYS liked the old behaviour: you can selectively add folders, files, and even folder in other paths and rearrange. I have been considering that old behaviour FAR better that bogus management approach of Visual studio, and FAR FAR better that IntelliJ / Maven logic (all crap in every sub-folder is good!!) I did appreciate you can move file dropping around the project: helpful to keep related file together. (think about views and controller in a MVC project, for example) A project IS NOT the contents of a folder, that is Finder logic! the new PACKAGE/SPM approach is rough, but acceptable, but honestly old behaviour has many good reasons to be. If Apple did change it to allow young developers coming from Java / maven or worst VS Code to use Apple ecosystem.. id a bad choice, IMHO. otherwise.. I wuold use jet brains IDEs to exploit that behaviour. :)
