Vulkan's main issue around using BGR is simple. The letters in the shader don't match up (rgba in shader, bgra in format). So of course, rather than allowing "bgra" or other permutations of formats in the shader, they went the nuclear option and spent months writing an extension to get rid of the need to have a format in the shader to begin with. All this to solve a problem that should never have existed to begin with. This fixes BGRA images since enabling WithoutFormat, as the GPU now remaps without your involvement.
