I don't think that's a controversial take. Ironically, I think it's when follow-ups are handled by the original creatives, they're more likely to take liberties and switch things up because the original isn't some kind of sacred cow to them.
Now part of my issue with Batman '89 departing from the source material was that the visuals were leaning way too hard into Batman TAS territory. It went beyond Easter egg territory to become distracting. They're similar in their tone and inspiration, but you can't just copy and past stuff without reason. Michael Gough, who has always been clean-shaven, suddenly grows a mustache. Michael Keaton's Bruce Wayne suddenly wears a yellow and brown suit.
All of that is to say that I think it's actually ideal that a fan is writing this. They'd know the importance of adhering to the source; just the fact that this takes place between movies requires a significant appreciation of the films.
