Rather than behaving exactly as configureForJackson2() does, I think we'll want it to set Jackson 3 up as close to how Boot 3.x used to set up Jackson 2 as we used to override a few of Jackson 2's defaults.

Good point, configureForJackson2() could probably be a good basis that we could refine with non-matching Jackson2ObjectMapperBuilder default configuration. Please let me know if I can help.
