This news, the only thing that lets me see, is that there are people who really have a lot of free time.

HelloDolly is inside the garbage that WordPress brings factory installed, along with the Automattic plugins that they are interested in getting through our eyes.

This plugin here does not make any sense, not even as an example of a plugin. The developer who thinks to make a plugin should look in the official WordPress.org documentation and find all the information, you do not need to "gut" a plugin that installs itself by default with any WordPress.

In my specific case, every time I do a new installation, I activate "Task After Install" and clean all that trash to start working.
