Did you watch Children of Earth? There's no way they're going to bring up Peter Capaldi's storyline in Torchwood in the family friendly Doctor Who...
Other Doctors may have been in the show prior to becoming the Doctor as well, but none of them starred as the Secondary Antagonist in 4 Episodes of my Favourite 5 Part storyline, potentially ruining it for me forever. How am I going to be able to watch that season again without thinking "That's the Doctor, That's the Doctor, That's The Doctor..."? It's going to take me completely out of it.
Suppose they could make some jokes about the Doctor looking like a Famous British Politician, but it's still going to stain Children of Earth for me.
