Feature suggestion - it would be nice if installed packages created a Scripting Define Symbol (found in Project Settings/Player/Other Settings). This would really help 3rd party editor extensions/tools authors when wanting to add optional support for installed packages in their tools. In our use case, we modified a popular project search tool to be able to filter by what was/was not an Addressable. Unfortunately this code will only compile if the Addressables package is installed in the project. This prevents the author from including this feature in the tool because the tool will not compile with our change if their customer's projects do not use Addressables. Thanks for listening! If we missed something, please let us know!
