When to use a forward plugin_end, and for what purpose .. I already read the definition but I still have doubts.

[fysiks]

Simply use it when you need code to execute when the map ends. For examples, you can look at existing plugins that use it.

An example is when using nvault. The vault file is typically opened in plugin_init or plugin_cfg. You need to close the vault on map change or server shut down so plugin_end() is typically used for this.

Most often used for freeing array, trie and other handles.
