Well, Chrome tends to be ahead of the curve on a lot of things. For example, you need to upgrade to El Capitan to get true flexbox support in Safari (or iOS9 on iOS devices). This coupled with the fact that Chrome users don&#x27;t need to do an OS upgrade to get the latest version means that you don&#x27;t need to do as much heavy testing on various versions of Chrome (in my experience... though it&#x27;s not in a locked-down corporate environment).
