Well, since I'm not a Windows expert, I can only give an intuitive
opinion. I think that we should start with patching support.unlink();
tweaking Py_DeleteFile() so as to do something more sophisticated than a
simple removal sounds like it could hide some behaviour change that
could hit some legitimate uses.
(as an aside, for higher-level variants of OS functions, the shutil may
be an appropriate recipient)
