Autowire all the things!
summary
Shows how a Symfony 2 legacy app with >1000 services (Nuvola) was migrated to autowire and autoconfigure, cutting about 5,500 lines of YAML. The migration is done in four steps: enable autowire per-file, add a legacy-alias file that declares public=true and class-name aliases, run container compilation to find and fix injection problems (entity managers, multiple implementations, setter injection, tagged/listener services), then enable service discovery and remove redundant service entries, resulting in a hybrid but working codebase.
