I use PS and ACR. When I need to use layers on a raw image, I have to go into ACR and back out to get directly into PS. It would certainly help if I could go directly into PS. I tried to get directly into PS by going into Preferences > File Handling and unchecking "Prefer Adobe Camera Raw for Supported Raw Files," but PS still goes into ACR with raw images. With that unchecked, it would be a very easy fix to have PS go directly into raw image editing.
