My question is: Is it really necessary to make big noises about retcons in your own fanfiction series? I mean, if you're just world-building and you haven't written a single story in your series that actually uses any of the characters and elements you established for it, can you really call it a "retcon" if you change things that contradict earlier information of those same elements and characters? I have been actively writing the EMPATH: The Luckiest Smurf story series since the 1990s, and I don't really make a big deal about any changes in the series since I already have an established history for the series, and I usually consider my stories to be in a "perpetual beta" state, meaning they are always subject to change whenever I feel they can be enhanced or improved with new or modified material.
