EU has been considered canon ever since it began its miserable existence.
Eh, not quite. It's only the modern EU which began in the 90's which was (mis)identified as canon. As far as I know, there was no canon policy for the early stuff made in the 70's-80's, especially since no real effort was put into maintaining continuity between the different books and comics written by the different writers.
