I am afraid that is the case. These APIs were introduced after 2.8.x was
released, and will be available in GIMP 2.10. The existing (non-GEGL) pixel
manipulation APIs will be removed in GIMP 3.0, which will follow after 2.10.
I recommend just making sure that the code that manipulates pixels/tiles is
clearly separated in the plugin and that they fit OK with the API model
that GeglBuffer has, to make porting when 2.10 comes out quick and easy.
