It doesn’t exactly need to be a secret plottwist, given the game literally starts with Simon’s brain damage, but there is also a bit of optional exposition about half way through about the gen 1 brainscans being primitive. Admittedly, it being consistent with the plot didn’t make Simon any less infuriating, at least for me.

Isn’t the smell just because the airlock dries out?

Not exactly the first time, given the incident a few years ago where a dog ran into the street and was struck by a Waymo. It got some publicity at the time but was forgotten relatively quickly, presumably since it was quite clear there wasn’t much any driver could have done in that situation. I expect this case will go over similarly, although maybe it will generate a bit more discussion since there are at least some imaginable ways this could have been prevented.
