It is unlikely to be removed from Co-Op for a variety of reasons:
Our Game has a Win/Loss Condition that exists when the enemy has 0 points.
Co-Op is generally taken as a faster, more aggressive choice. The 0 point Win/Loss Condition keeps the match times down.
In order to lose enough point to reach 0, a Team must be at a significant disadvantage and tracking down the last 1 or 2 ships can be tedious.
The most common concerns I hear are about being nearly able to DevStrike a ship when the match ends, or having some other highlight moment cut short. The reality of the situation is that most/all of your teammates have run out of things to do since most of the Bots are dead (if you're approaching a 0 point situation).
If you have a specific replay you'd like to show which highlights a specific problem, please post it. There may be other ways of accomodating issues that are more specific in nature.
