You can get 'layover' times as low as 50 minutes sometimes so 70 minutes should be fi
Personally, even if the airline schedule allows, I would always go for 2hours transit at a major airport.
Departures won't wait for a few late pax. Maybe for a large group travelling together.
Your 70mins can soon reduce with a slightly later slot ex EDI and a hold on arrival into CDG.
I'm sure now that I have said this that all will be well, but I prefer the more leisurely transit and a better chance of my bag making it as well.
