Brightness/Contrast no longer exists as an adjustment layer. Why? Bug or feature?

It’s there but it’s not easy to adjust. From what I can tell it can only be applied on a single layer and not adjustable if the layer is rasterized. I’ve always had a single adjustment on top of a group of images to be able to quickly edit the value as needed when I work through my layers. You can adjust it if the layer is a smart object but then you can’t make edits (like cloning) if it’s a smart object. So now there has to be workarounds just to make a simple adjustment to the brightness and it’s annoying. There doesn’t seem to be a good reason for Adobe to have taken it out of the adjustment properties when most people probably use Brightness/Contrast more than say Channel Mixer. 

Read the link. If you follow the forum by email, then you won’t see it because I added it later, so here it is again: https://helpx.adobe.com/photoshop/desktop/create-manage-layers/color-adjustment-fill-layers/adjust-image-lighting-with-light.html. You can still create the legacy adjustment layers. About half way on that page.
