Then again, Trek is rife with examples of unexplored territory that is explicitly mere hundreds of lightyears from Earth - Pollux, for example. And Trek even offers us clues as to why this might happen: the Spatial Anomaly of the Week could be blocking the path of our heroes in certain directions.
Such spatial anomalies can come and go, as happened to the Delphic Expanse. Perhaps a block behind Deneb Kaitos just recently evaporated, allowing Starfleet to mount an exploration effort in that direction, and even prompting it to hasten the pace by outsourcing the support base system.
Certainly we shouldn't draw the conclusion that, just because we see a starship at location A at distance X, Starfleet should be assumed to have explored all locations between Earth and A, or the entire sphere to the radius X from Earth.
However, the case of the Hood is a bit different, because it wouldn't be reasonable to assume her to have loitered to a very distant location at a relatively slow pace long before the E-D. The fact of her ferrying Admiral McCoy around goes against that.
That is, unless somebody writes a novel about the epic journeys of the geriatric old fool at the very limits of Federation reach, culminating in the scene where the whitejacket people finally catch up with him at Deneb IV.
