No such thing in my opinion, this is no different to when in combat you take out what you want and leave the junk. It is just a mere inconvenience to the next person who wants to mine, but again like in combat they will eventually spawn again..
Most MMO's make me laugh in situations like this, if there is an exploit or a quicker way of doing things, players WILL find it and use it. It usually only gets classed as the above once players themselves start complaining or if the Devs realise it shouldnt work that way, then its up to the said Devs to fix it so it works the way it they wanted it to.
If it is really a problem for people, heres a suggestion, once a player opens a roid, make the said player be stuck to the roid till its empty. problem solved (till he runs out of vault space then it becomes an inconvenience whilst he trashes the stuff he dont want), but then we do the same for combat of course...
