Yes, this is consistent with lore (IMO) - there is no FTL coms and the only things that are FTL capable are our fsd_equiped_ships - which means we need to personally visit a system for exploration data and dock with a station for trade data - or we can purchase those bits of Info from the Sysmap which acts like an information broker.
Also consistent with the data courier missions, although a special case can be made for the extra security offered by ship delivery of said data as opposed of using a transmission that can be intercepted/decoded.
But then again it is inconsistent with the lore since apparently the Imperial Senate was able to hold realtime telepresence meetings, Palin is effortlessly able to reach us 5000ly out in the black when we (more or less intentionally) unlock his services and not at last, we have instantaneous telepresence anywhere in the galaxy even from bubble to the Beagle Point
