The traditional approach in Java has been to let those things happen in third party space, then form an expert group to standardise a shared API for them. That was done with XML parsers and ORM fairly successfully. It doesn't always work, as with your examples - there was an attempt with logging, but it was done badly, JSR-305 ran around, etc. But I think it's a much better approach than the JDK maintainers trying to get it right first time.
