As of Sept 2024, Safari 16+ supports HTTP3 for all users.
Previously, a subset of users had support enabled (as long as they had Safari 14 or later (including Big Sur or later for Safari on macOS). There was a feature flag available in Safari 14.0-16.3 that allowed users to force HTTP3 on (it was removed for Safari 16.4+). Unlike other feature flags, having the flag off did not disable HTTP3, it just meant maybe the user got it, maybe they didn't.
It's complex to communicate all this in a dataset that assumes features ship with a new version of the browser. In this case, the changes are on being made elsewhere, and are not dependent on updating the browser.
