An alternative might be a flag on rename: overwrite=['always', 'os_default']
How about overwrite=[None, True] with None meaning "OS default"?
with a warning and a switch of the default in a subsequent release.
I think we should be conservative with warnings and compatibility-breaking changes. In this case there's no pressing need to change behaviour: the default isn't less secure or less efficient.
