Comment (by helen):

 @TimoTijhof Thank you so much for this concise explanation and clear
 example of what can happen. I suspect we have similar practices in
 userland, in particular in themes, which don't get very much pre-release
 testing outside of the default themes.

 I'm leaving this open through RC so we continue the effort to communicate
 this outward and see if there are some static searches we can run against
 themes and plugins to find potential problems (example from
 @TimothyBlynJacobs:
 https://wpdirectory.net/search/01EQ9BZ9BTWZRDE8D225FC3W1M). I'm definitely
 a little skittish after seeing the fallout from 5.5, such as with
 `.live()`, which despite years of deprecation notices was still widely
 used. I think this is probably a significantly smaller issue than that but
 I'd rather show mindfulness.
