Well, I think what the blog is referring to is the fact that there's no stable supported API yet. However
there exists an unstable API and I think the best way to make that unstable API stable is to use it, provide
feedback if it needs changes and otherwise report back to the gstreamer folks that it's working great (in case it is),
so that they can get confidence in it and declare it stable.

That API is now called GstSurfaceMeta (see gstreamer-1.0/gst/video/gstsurfacemeta.h).
