Added to Weston is the currently experimental linux_dmabuf extension for creating DMA-BUF-based wl_buffers in a generic manner. There was the protocol add (likely to be merged into Wayland proper once stabilized), DMA-BUF importing for the gl-renderer to import as an EGLImage, and X11 and DRM compositor support.
See Collabora Looks To Add DMA-BUF Protocol To Wayland for the background information and explanation on this feature for Wayland/Weston.
