Meta Quest

It does seem strange. It may be a liability issue - easier for Meta to make it entirely the users responsibility to clear an area rather than meta be responsobke for a safety system that should show you objects but may go wrong.

The example of it not showing the dog is a good one - if you trip over the dog and hurt yourself who is liable? If you have a system that shows objects and people/animals in your play area then it has to work 100% perfectly and Meta is responsible for making sure it always works. While if ypu say "thats your problem, keep your play area completely clear", and remove the feature, from the get go it makes it harder to sue Meta if you get injured. Having no Safe Sense system takes any responsibility and potentially liability away from Meta.
