Well, from what I'm gathering about the prequel, there might be some critical details about the Titans, and perhaps about the outside world, that could've been systematically suppressed in the decades after the incident.....because one thing that's mentioned in BTF is that the incident that transpired (of the Titan coming into Wall Maria) was forced to be forgotten, hence why there is no reference to this incident in the current AoT manga series. Plus I think the Wall Cult has a huge influence in government affairs in the current series, some of which might be further explored in BTF.
