 Replying to [comment:53 mor10]:
 > If `async` or `defer` are used, they are added to the script tag as
 booleans without values:

 A reminder that even the W3 Recommendation for HTML 5.2, includes coverage
 of XHTML syntax (XML-serialized HTML), which, among other things required
 by XML proper, disallows boolean attributes.

 There may well be other issues that stop WP from being delivered as
 `application/xhtml+xml`, but let's not introduce new code that moves core
 output further away from polyglot markup.
