These new sites are designed for salvagers and they would be lore friendly as it has hinted in some missions some corps abandon there buildings in space due to its simply much cheaper compared to breaking it down.
Well surely if this happens sites must appear around new eden where salvagers can locate them enter them and start breaking down the buildings and maybe even some left behind wrecks.
Meanwhile in wormhole space such sites would have sleepers lurking as they move amongst the wreckages even to the point you might run into a graveyard of wrecks.
Actually, salvage sites from “long forgotten space battles” would be quite awesome as a lore idea and would add a play style for people who like that sort of stuff. Wouldn’t be for me but that’s not important.
Could even open up an avenue for more salvage ships, perhaps sneaky/cloaky ones.
