The only concerns for me would be random small shops that aren’t hit by anyone running the scanner. Does the scanner get the data from just the shop stands loading in your draw distance, or do you have to look at them? The playing field has to be equal, giving a shop an advantage based on your ability to send data to the site might be seen as discriminating.
edit: Basically the ideal solution would be to have all data so it’s fair for all, but only the devs can do this atm so for that we’ll have to wait for the ingame solution. I’m interested in how close and how easily does the scanner get to that ideal.
