Why do so many VR games don't show arms???

Till this day I still dont understand why developers do this. It just makes every game feel unreal, and it makes it difficult for me to really feel immersed.

Games like Walking Dead Saints and Sinners show arms are perfectly possible. Even if it would be difficult to construct in game, I would still prefer a weird looking arm instead of some floating hands.

Am I the only one thinking this? Or am I missing something?
