Marion, I have joked about CDO for decades, even while wiping every teaspoon on the table three times, even though they just came from being washed, or lining up the cutlery to the exact same distance from the table edge.
Not joking about joking about not joking about it can get so convoluted it becomes in itself a form of CDO.
Needing to get rid of those outdated comments is another form, albeit a mild version (for some). Needing to line sources up, so they are all indent to the same level, and not all higgledy-piggledy so aligned full left, some indented, is another.
(Trying to stay on topic so we don't get dinged. )
