I agree, but if fans like us can dedicate the time and effort, they as the creators should too, not to mention they have the absolute ability to retcon, explain and reason placements. Looking at this way I would rather take that they don't touch anything if they are going to just screw everything up because they half-ass it. But even if they don't map everything out, at least subtle nods of the existence of other products would be welcome as well.
And then there is the option to just say they are different universes and then they don't even have to bother placing them. After all the description of the book says "Different worlds, different timelines". I'm just thirsting for any recognition regarding AoS, Cloak and Dagger and co.
