If a client uses an older version of the dmabuf protocol, use the `formats` event instead of `modifiers` (since that didn't exist in older versions). With a bit of necessary guessing, support dmabuf importing even when EGL_EXT_image_dma_buf_import_modifiers isn't present instead of failing up front.
