All canon, is canon until something contradicts it. The Illiyan Nastase thing is patently nonsense like a lot of Rogue Trader stuff, but is still legit until retconned, rogue trader is not 'semi canon' it is full canon unless specifically retconned, such as imperial dreadnoughts being more akin to suits of armour you could take off (they had ejector seats, and even jets in their feet so they could act like jump pack infantry and also were not exclusively space marine)
