Interestingly, Moffat does describe himself as having a particularly strong attachment to old Who canon, even though he hates the 6th/7th/8th Doctor eras. He described himself at one point as being "physically unable to contradict" anything established as canon in old Who, even if it was rubbish. He was basically saying on a panel thing years ago - right as he was preparing to take over - that he wouldn't have dared shatter the canon with things like the Time War himself, even though it was what was needed.
So it's no surprise he's been a bit more reverent, I think. He clearly has a lot of love, and a lot of respect for the lore of even the bits he didn't care for.
