Given Ralph and Piotr are strongly opinionated about keeping `log4j-api-3.x` binary compatible to `log4j-api-2.x`, can we not release `log4j-api-3.x` in `main` and make `main` only depend on `log4j-api-2.x` instead? (We can move the contents of the `spi` package in `log4j-api-3.x` to a separate `log4j-spi` module in `main`.) This will make everything crystal clear:
- Log4j 3 is just a major improvement over the backend - Log4j 3 still supports Log4j 2 API - We can move the Log4j 2 API to a separate repository with its own release life cycle (ala SLF4J) - When time comes to make a new Log4j API where PMC agrees to make breaking changes, we can call that one Log4j 3 API I would appreciate it if you can help me to understand if I am missing something. Otherwise, I would like to know why we need to make a major release for a project that is identical to its previous version.
