Comment (by afercia):

 Worth noting the REST API response return by default ''all'' the fields,
 even the ones that in this case are not needed, while the traditional old
 AJAX way returns just the terms. Quickly testing on a VVV install,
 searching for `co`, here's a quick comparison:

 AJAX: 430B, 112ms
 {{{
 claycold
 Codex
 comments
 content
 shortcode
 }}}

 REST API: 3.6KB, 168ms

 I'm really not an expert about the REST API, just wondering what is the
 advantage in using them ''in this specific case''.
