Comment (by melchoyce):

 We'd like to resurrect this for 4.9. Some ideas:

 If you're editing your theme:

 > Looks like you're trying to edit your theme! We recommend creating a
 [child theme](link to documentation) instead. This will let you make
 changes to your theme without accidentally breaking anything."

 Except with better copy. 😅

 We could consider making a "make child theme" button that generates a
 child theme with a functions.php and style.css.

 Once someone makes a child theme, whether manually or using this button,
 we should link to the child theme documentation at the top of the screen.

 If someone's specifically editing their style.css, we should consider
 showing an additional warning to directly them to Additional CSS:

 > Hey, did you know there's a safer way to edit your site's CSS? Check out
 [Additional CSS](link) in the Customizer.

 If you're editing plugins:

 > Looks like you're trying to edit your plugin. Editing this code is
 highly discouraged; please proceed with caution and make sure to back up
 your plugin before making edits.

 (Though I have to say, the brevity of "Caution: You can break stuff here"
 is appealing.)
