Ok first, It was very important. This has *SPOILERS* so dont read this if you dont want part of the story ruined. The 3 ships have AI's and navigation databases in them. Since the stations ai's were flatlined as soon as covenant entered Reach, there was no way to destroy the nav databases. In essence, there is a chance that the covie found out about Earth from coordinates from one of these 3 ships.
