I'm not sure which I find the most bizarre
As is, the behaviour makes it impossible to safely rename a file.
You can test existance before issuing the rename, but in any multi-tasking environment there is always the possibility that the target file will be created between the test for existance and the rename. This renders the the often hard won (and IMO, sacrosanct) atomicity of the OS rename API useless.
This rates up there with non-exlusive-opens-by-default and cooperative locking as remnant bahaviours of a bygone era that should have been superceded long ago.
