Atleast bombs are somehwat trying to be weapons so atleast dropipng them should be okay.

I currently think that dropping containers is only restricted by the PvP flag. I know that a agressor can start locking you and you can still drop a container. I am guessing this is the reference. However I fail to see how this would counter as "being in combat".

I could agree that there could be introduced delays or that a field container needs first to be "activated" to accept cargo like beacons do.

This is fine line of using less used features in a programmed forsaken game,such as transporting cargo in beta. You can't really be sure that what you have in your hands in an intended feature.
