I fall into the other camp. I like exists_ok=False because it is safer
behaviour.
If I'm writing code which expects to make a directory, I _almost always_
want that directory to be _new_ and empty, unused by some other purpose.
If exists_ok were True by default it would be very easy to write code
which accidentally used a directory belonging to something else.
I would far rather such reuse required a little thought on my part, by
requiring specific calling out that exists_ok=True.
