Also with all this new AI stuff it should now be possible to make a brush who separates background from hair at once without all these go here go there do this do that. Just 1 brush with a for example ALT function who marks a part of the keep area and colors, (not the whole subject object) just a part of it or multiple parts. so the AI has something to work with. And a CTRL function doing the opposite (marks the remove areas and colors). this way you have everything in 1 little brush and some shortcuts. No dropdowns labyrinth here and there. We could call it a "Content ahair brush" or "Hairbrush" (that was a joke :P) see the attached demo image
