Doctor Who showrunner Russell T Davies has spoken about his willingness to break the shows six-decades of canon in future episodes. Davies return to head up the worlds longest running sci-fi series has already seen him tearing up the TARDIS rulebook, with the return of David Tennants Doctor during the 60th anniversary episodes, and the bi-generation incident that led to the arrival of Ncuti Gatwas Fifteenth Doctor for a whole new era of Disney-backed Who. It seems that he is not done playing with the contradictions and conflicting situations that can arise when playing around with a time-travel show.
