Likely would be configurable since I can see why it isn't a thing but by letting circles consume wisp to store media it would be easier to have circles collect media and distribute to along wisp pipelines to other circles.
Currently for sending media to other circles gtping/gateing media items or shulkers of them, or using return item with a mote nexus are the only ways, but I think this way to harvest media from slipways more permanently and have cooler media transmission between circles like this would be cool.
