To be fair, I do this in Solo, cause theres really no need to do this in open. But if one would do it in open, I can see how it could be a problem at outposts. Stations on the other hand do have more landing pads than the max number of players that can be in an instance if I remember correctly, so that shouldn't be an issue.
This was the situation at Ito Orbital not so long ago...
Not a problem... yet. But this was 3PM in the afternoon. I can see it getting quite a bit busier later.
Add the shield issue and even some stations might get a bit crowded.
