At the time of The Root of All Evil's release, the Krynoids had only appeared in two Doctor Who stories. Same thing with the I in I Scream.

Do Not Forsake Me Oh My Darling!, The Quality of Mercy, Miranda, and The Winning Side all feature characters who had only appeared once in a Doctor Who story at the times when they were released. Also, if this written off as a "author uses his own character in a probably non-DWU story" case, I'd like to know why it's different from Enter Wildthyme, a novel by Paul Magrs which brings together many characters/locations/species from his fiction, many of them just happening to be from his Dr Who novels. If you were to do that, you'd probably need "Extraordinary non-narrative evidence — such as the story's author directly saying that the story doesn't happen in the normal DWU".
