Comment (by superpoincare):

 I found out that the code checks whether unicode9 is also supported:
 https://github.com/WordPress/WordPress/blob/ea6e749c7137f1acd7570f78b4ea756e65adace0
 /wp-includes/js/wp-emoji-loader.js#L98

 So wp-emoji-release.min.js should be loading in Chrome on Mac, as is the
 case now. Works as expected. ✔️

 About loading asynchronously, I checked load times by explicitly using
 {{{
 c.async=true;
 }}}

 in the final output. This doesn't change much, implying that the script is
 anyway loading asynchronously. ✔️

 So I think the only possible source of delay - if at all there is one - is
 if it takes time to feature detect.
