I disagree completely. When implemented by the browser itself, it's straightforward to ensure all the relevant events are still fired without presenting the actual animation to the user. As for the list you brought up, a loading spinner spinning and the like is exactly what should be disabled. These are not interactions that are necessary for the site to function and they bring harm to some users.
