Hello @LeanderFS, thanks again for your contribution! This issue was addressed a different way in PR #942, which removed Mozart and replaced it with PHP-Scoper. As a result, the plugin dependencies, such as psr/log, are now scoped automatically during the plugin build process. While the development codebase remains unchanged, the final plugin package is built with scoped namespaces, resolving eventual dependency conflicts.
This will be included in the upcoming update and can be tested with the 7.8.1-beta version from here.
We appreciate your effort in addressing this issue and hope that this solution suits your needs. Don't hesitate to let us know if any doubts remain 🙏
