Then it becomes a personal option. And to that there should be no arguments.
Is it technically needed, no. Do you feel better doing it, yes. Your choice!
Most 335d sold in severe winter areas have the 'cold weather package' (heated seats and steering) that certainly adds thermal confort to cabin in extreme situations.
I probably cannot be considered as a standard sample for users, as my cabin temp set up is 62F
