+1, assuming the deprecation lasts for at least two versions and the available alternatives are explicitly mentioned in the What's New entry (for both the version they're initially deprecated in and the one they become removed in). Although, I suspect that the deprecation may need to be longer than two versions from possible breakage in older libraries or legacy code. They don't seem at all common compared to shutil.move() and shutil.rmtree(), but I do vaguely recall seeing some usage of os.renames() and os.removedirs() in third party code.
