In follow on CLs we need to know what the load op is when we try to use discardable msaa attachments. For vulkan the load op affects how we copy the resolve attachment into the msaa attachment, which changes the render pass we use (adds extra subpass). We need to be able to make a compatible render pass to compile programs.
