The next composer release next week (you can try `composer dump -o` with snapshots right now) warns a bit more about classes which do not match the psr-4 rules they are found in.. Symfony has quite a few false positives there because the rules are using `""` as path for all individual components so all files of the component are scanned by default. I already made sure Composer excludes the vendor dir by default now, and this fixes the rest of the errors I noticed.
