Comment (by darrenbrettking):

 In addition to the YouTube shortcode issues, I noticed issues with other
 themes I use as well - including this one:
 http://demo.themeum.com/#starter

 Note: you won't see the issue on their live demo because they haven't
 moved to 4.4 yet, but I saw it on some of the sites I'm hosting.

 Question: larger picture, can someone help me understand how this relates
 to the WP commitment to backwards compatibility? My understanding is that
 it's up to developers to update the PHP code to handle the shortcode
 issue, right? Just wondering how that fits with the overall commitment to
 sites not breaking with updates. Thanks!
