Comment (by celloexpressions):

 There are numerous popular CSS plugins, many of which leverage the
 customizer: https://wordpress.org/plugins/search.php?q=css. At a glance
 many (most?) don't sanitize CSS. I should note here that probably the most
 popular is @johnregan3's, which has over 300,000 active installs (and his
 work to add customizer support transitioned into working on this for
 core).

 The combined popularity of these plugins is a strong argument for a core
 need for this functionality, especially when considering that it is an
 improvement over and extension of the existing code editors in core. If we
 can move forward with bundling the two libraries we need (CSSTidy and
 CodeMirror), the core solution will offer a better combination of security
 and user experience than any plugin currently does (some use the
 customizer with instant postMessage previewing, some have code editors,
 some save CSS as posts, some sanitize, but I don't think any do all of
 those things).

 Looks like Tailor also uses CodeMirror; seems like that's a good option
 here.
