My opinion says there's a lot What if's, Lets say your a Miner and get destroyed, meaning not able to finish emptying the asteroid, or hulk, an or the Server goes offline, or the Individual CTD, or had to log off for one reason or another, not necessarily cherry picking is it? perhaps the individual can't find their way back to the certain asteroid, or hulk after they came back? or their cargo hold full had to empty at the station, then someone comes along says wth, lets see who mined last so I can flame on them, when all their doing is emptying their cargo.
yup a lot scenarios to be sure of, not saying it's a bad thing to have that command in place, all am saying there's a lot room for misgivings or wrongful blame an abuse.
I for one always empty out the entire field, hulk fields too such as they are, hulk fields are few, and far inbetween now since we went Live any ways, 90 percent of the Hulks only have Debris in them to start with, they spawn like that
This is just my observation
