Comment:

 I'm concerned about the potential for negative side effects this could
 have on sites.

 Any site that targets `section#primary anythingelse {}` would see their
 theme break, and potentially severely because this is a high level element
 in the DOM.

 Any site that uses Twenty Nineteen and has any custom CSS defined either
 in a child theme that does not override all of these templates, or added
 through the Customizer could be effected.

 This could be a low number of sites since Twenty Nineteen is relatively
 new, but I don't know that we can safely roll out this change without very
 advanced notice.
