I've quoted the most important phrase from your post. Not necessarily in the right order.
They did not know it was there - there may be an alternative universe where the MDT met and did know it was there, but we can't get to that universe, and besides whenever 'Red dwarf' went to an alternative universe there were monsters.
Not relevant now - correct, you should never worry about something you can't change, and you can't change the past.
You should use the past to learn what to do in the future, but you will never be in this situation again so I think you can safely ignore any lessons from this. However other members, yet to make a decision, can learn that not all scans are accurate and factor this into the decision making process.
