Another thing which just came to mind is that after the whole Astronaut story, the Doctor started erasing records of himself, making himself unknown. This eventually led to River being released.
In Asylum of the Daleks, Clara erases all info about the Doctor from the Dalek's hivemind.
Since then we've only had the Great Intelligence who seems to recognize the Doctor in The Bells of Saint John, but that's only because he had met him again in the Snowmen. The rest were only one off monsters and the Angels, who don't really seem to give a shit about who the Doctor is.
I don't have a point to all of this, just thinking aloud.
This just seems like something they need to do from time to time to be able to still write stories where the Doctor isn't a universal celebrity.
