Spring Boot offers nice abstractions to configure logs via a unified model. Furthermore, it offers great integrations and customisations for Logback and Log4J2.
The recent addition of structured logging brought many benefits. I wonder if the work that was done for that feature could lay the foundation for implementing a new feature supporting bridging the logs produced by SLF4J/Logback/Log4J2 via the OpenTelemetry API, considering that Spring Boot 4 comes with auto-configuration for OpenTelemetry Logging API and OpenTelemetry Logger Exporter API for OTLP (but no logs are actually exported).
