I don't think `prefers-reduced-motion: reduce;` should block gifs from autoplaying. Gifs for better or for worse have been used for the last two decades on the web, and they may hold critical information on a frame other than their first. The better approach here would be to add another option here such as `prefers-reduced-motion: enforce`, which overrides the page's preferences, at the risk of breaking the page. This would be similar to how a forced high contrast mode works today, which overrides a page's styling. This would guarantee that `reduce` doesn't break any existing experiences, while still providing the option for those with vestibular motion disorders. I actually like Safari's approach with the img tag - gifs have been used as a backup for no-sound autoplaying video for years now, leading to so much wasted bandwidth and poorly encoded "video". At the very least they're giving a suggestion that would alleviate that issue.
