[40k] Is the Emperor's origin canon?

Is the Emperor's origin as the result of the reincarnation of the shamans of old still canon? Or is GW planning on retconning it like the rest of the aspects of the Emperor?

Maybe? Maybe not? 

Shit, even if it is canon it might not be true, 40k is real bad (or good, depending on how you look at it) about having unreliable narrators.

What is canon is that the Emperor showed one of his custodians a vision of the emperor as a child in ancient Anatolia, and even then he had psychic powers.
