Suppose you are working on multiple fixes meaning you are installing multiple packages for different purpose all this done over a weekend. So if you use standard dnf to handle that it will do cleanup in chronological order not to mention the time spend on untangling packages from memory to identify where you used it. This is where Labeled shines!

Labeled treats installations as isolated, logical tags rather than a single linear timeline. You can tear down session A while keeping sessions B and C completely intact, regardless of the order they were installed.
