The problem with listing movable stations from the journal is that it'll tell you that a player visited it while in X system, but there's no way to confirm that it's still there.
Manageable when it was just the Gnosis and the two "Bridging the Gap" ferries, which all only move once a week in a predictable fashion.
Tracking thousands of stations which can jump every twenty minutes and be renamed at will is going to be very tricky to have any useful data quality with, and it'll be interesting to see what happens to handle that (I'm planning to just ignore them on mine)
I think the folks that run EDSM were going to list ships in DSSA as POI's.
