The idea of The Author as the final arbiter might be the historical oddity.
The genre of Greek tragedy took characters and events from the Homeric epics but created original works elaborating on specific events and characters. By modern standards we might call this fan fiction, but the Greek did not consider it fiction since these were supposed to be historical events.
I’m annoyed by the amount of sequels and prequels and reboots in the cinema, but I recognize that Shakespeare mostly remixed existing stories and still did pretty well.
