My team has been using AI to add code, but also to aggressively remove old deprecated code. "Is anyone still using this? How does this get called" is easier to answer when you can toss your FE, BE, and entire codebase at an agent and let it create a map of your software project. IDEs can do this in a single language to some degree usually in a single project, but RPC, REST, etc... break some of these tools in a lot of IDEs.
