Description
There are only a few endpoints and none of them is very complex. It would be nice to have an annotation (reflection) free implementation. Wouldn't make much difference to most Spring Boot apps in a regular JVM, but it has a bigger impact on native images (where @RequestMapping is expensive).

Research direction
Start by locating BasicErrorController and mapping the few endpoints it currently exposes. Review the surrounding error-handling tests and native-image considerations, then verify that an annotation/reflection-free implementation preserves the existing endpoint behavior and works for native images.
