Who did they mislead? A few days later it was no longer experimental and it became the main dev branch as they decided it would be the way forward for development (see the blog post on why). No stable release has been declared yet.
Here was the Bun team's message on merge:
> It passes Bun's pre-existing test suite on all platforms (and fixes several memory leaks and flaky tests), the binary size shrinks by 3 MB - 8 MB, the benchmarks are between neutral and faster - and most importantly, we now have compiler-assisted tools for catching & preventing memory bugs, which have costed the team an enormous amount of development & debugging time over the years.

> The codebase is otherwise largely the same. The same architecture, the same data structures. Bun still uses few 3rd party libraries. No async rust.
