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.

But this fragmentation is what needed to make good software. If you put things in the standard library you're just adding a +1 to the fragmented landscape because for instance it will never be specialized enough to cover all use cases, so people will still use their own libraries, just like for instance c++ has three dozen distinct implementations of hash maps just because one cannot fit all cases
