Which image layout should we use for shader image load stores?

As far as I understand spec 1.0.48 only the VK_IMAGE_LAYOUT_GENERAL can be used for that purpose, the term "must only be used … " limiting all the other layouts. True? No optimized layout for shader image load and stores?

Found it my self, section 13.1.1 states: “Load and store operations on storage images can only be done on images in the VK_IMAGE_LAYOUT_GENERAL layout.”
