Different analyses can indeed produce the same lattice. However, we have some common combinations, such as using ConstantPropagationAnalysis when performing DeadCodeAnalysis, as its results are sufficient for DeadCodeAnalysis. If further analysis is needed, users can still choose to load additional analyses manually. This approach simply provides a set of default dependent analyses for some analyses.
