Pretty much agree that some type of coarse/basic ID needs to be available from the Ship.
Since taking the SRV into "yet another Cargo dump" (not what you need/you're looking for) is a distinctively bigger investment of (waste) time than i.e. Signal Sources in Space, I'd vote for any means to get a rough idea and sort out the ones that are definitely the wrong type.
In space, we have easily identifyable types of USS - and what we have on the ground is 100% identical in nature. With the exception of almost not having the slightest idea what kind of POI or POUI (Point of UNinterest) we'll encounter.
I've frequently parked the Ship in the center of the blue POI circles during my tests and it took me Minutes just to spot anything remotely "POI" on the Wave Scanner (driving circles 2km around my Ship basically) - very often with nothing viewable from the Ship.
POIs all by themselves are a very weak mechanic in their current incarnation (and often don't make any sense depending on location), so at least helping out when they're a Mission target is definitely in order.
Unsure if their size is already intended to work into that direction, though.
My impression is... that this is actually the intended "Pre-ID" criteria that just requires Players to build experience onto what to expect based on small/medium/large sized blue POIs on the Ship scanner.
Outside of Missions - I downright ignore them for the time being.
I currently see them as spammy and location-unaware like the USS were back in the very old days, shortly after they were implemented.
But should I ever be in need of unlimited tons of Tea, Narcotics, Personal Weapons or Animal Meat for some wicked reason - they'd be my first Target.
I'd rather save me the time and purchase those in bulk, however.
PS.
Since we're running V2.0 , I guess we'll see them getting some finetuning in future updates anyway.
After all, nothing beats entering an entirely Unexplored System (no 1st discoveries) far over 1000LY out, just to see every landable planet littered with man-made junk already
