I don't think FDev is asking us how specifically they ought to realize this new function and I'm pretty sure the design is 'ready to go', only asking us for feedback about how it works and how we like it. Don't worry, they still design the game, not you.Given the way it works already:
I would think there is the possibility of a three-stage notification. First you get a "Likely", then you get "Present" and then "24 Geological".
- Some bodies scan instantly with no POIs
- Some bodies scan in 2-3 seconds with no POIs
- Some bodies take 20-30 seconds with POIs
That would mean getting information from the running GPU process though, and I think that would be a problem. It might be possible to do it based on run-time, just as we do now, but we wouldn't know if the extra time was because of Geo sites or Bio sites -- it couldn't differentiate them.
All in all, I'd prefer the proposed system with additions to report on the number of sites on the System Map.
Having the surface generation wait until DSS makes logical sense, but it's a big change to the game-play and it's unnecessary. FD have always prioritised game-play over simulation veracity. Look at multi-crew for example; you don't have to be in the same place to join a ship. Holo-presence is the only interstellar FTL information transfer that exists in the game.
Additionally, it makes no sense that the number of POIs is only reported in the FSS. It should always have been in the System Map.
Agreed with your last point though (POIs also should be prominent in the system map). For some strange reason (meanwhile by tradition now) they always had a hard time to sync data representation whenever it was redundant and shown in different locations. As if they would have a separate team for each window section and there's a big lead wall between them. In other words: to me it often looks like they seriously need to update their inter-team communications...
