Well, a coop mission, by my definition, is player versus a.i. only first of all. Second, it has a determined starting time so that pilots are able to fly in formation in a semi-organised way without waiting for folks who do not arrive on time or for any other reason. Third (this is more as it relates to ATAG server to give a direct comparison) it is not just several bomber objectives placed around the map, but an actual mission with varying conditions that must be met in order to succeed.

Now, this is not to say ATAG is wrong in any way, but it is not what people are asking for when they request coop.

Edit: obviously it is known that these things are possible with the toolset we have, however it requires all of the following:
1) map made, mission coded, and tested, by players
2) a server to host it on
3) recruitment/advertisement to get folks who would not otherwise know of its existence
4) precise planning and outside-of-game briefing to ensure folks know what to do, as current in-game briefing doesn't seem to suffice (can you get pictures in briefings? I'm not sure)
