I think the trouble is that in alot of ways Voyager is a step or two behind DS9 in its take on those events, even though cosmetic details (like the comm badges) indicate otherwise. In terms of its writing, "Caretaker" seems to take place within spitting distance of TNG season seven, what with all the build up about the Maquis and everything. It follows quite naturally from the events depicted in TNG "Premptive Strike", which makes sense as VOY was in development during that period. But DS9 "The Jem'Hadar" and DS9 "The Search" really do blow the flood gate open in terms of expanding the Alpha Universe mythology in a whole new direction, and VOY unfortunately starts out from a point which feels several steps behind
those galaxy-shattering events. It's all a bit of a muddle.
