We'd love to be able to add some form of visual warnings to games with artificial locomotion, notifying them of the possibility of motion sickness.
As of now we've tried to avoid having too many games with artificial locomotion in our selection, but if our customers could be warned about this before opening the game, I think we wouldn't have to worry so much about adding these games.
Of course the warnings could be used for other things too: jumpscares, flashing lights etc.
