Funnily enough though a lot of web developers really hate Apple for this (going as far as claiming "Safari is the new IE" which is just ridiculous). But as a former Pale Moon developer I think Apple is the "lesser evil" than Mozilla exactly because they're "slow" in implementing the latest "Living Standard". Oh and just like us they've rolled out a JPEG XL support enabled by default in their stable release before Mozilla and Google did ;)
