It would actually act as a shortcut from inside X-Sector, it's a shorter distance to walk than exiting X-sector, walking past the Towers, past Hex and TWODW. A path from around where Enterprise is now, entering the new area near the Flag Tower wouldn't interfere with any of the buildings currently in the area. There is an access road around there which would be the only real problem, but there are ways around that, bridge, tunnel etc....
Sure it probably wouldn't be the main entrance to the area, just one of them.
