We already have a new version of what is the experimental Safari browser. Apple created this version to be able to test it and not Safari itself so its functionality would not be compromised. Thus, in this way, the novelties were tested in a safe environment and the final functions were transferred to the base Apple browser without problems and with the necessary corrections. Right now the American company has just launched Safari Technology Preview 144. If you want to try it, it's easy, although there aren't many new features in this version, some interesting ones have been introduced.
We already know that beta versions of software for devices are usually tested first by developers. It is not for less, since they are the ones that must adjust their programs or applications to the novelties that Apple is introducing in those programs. With Safari Technology Preview 144, the same thing happens. It is the developers who can test these new functions, which in the case at hand are basically bug fixes and performance improvements for Web Inspector, CSS, Web Animations, JavaScript, WebAuthn, Web API, Accessibility, Media, Security Policy and Web Extensions.
