The visual interface was meant to be a generic mechanism for specifying the content of a buffer. It goes back to before we had the buffer factory interfaces (like wl_drm and wl_shm) and we wanted to keep it open-ended enough that yuv, png or even svg buffer or so would be possible. Now that we have the buffer abstraction, we can add different buffer types by introducing new interfaces that create buffers. It only makes sense to leave it to those interfaces to specify the contents of the buffers. For wl_shm, this means that we now just specify the pixel format using an enum. For EGL buffers, the exact pixel formats are controlled by the implementation (part of wl_drm and similar), and from the client point of view, everything is controlled using EGLConfigs.
