Now, yes.

Until now, removing an open file was a legal thing to do. In fact, not 
only was it quite common, it was even the recommended practice in some 
circumstances.

I don't think you can remove an open file on Windows. Thus, you can't 
rename something to an open file.

Each case where this happens has to be analysed: is the renaming 
intentional or accidental? If it's accidental, it's a bug. If it was 
intentional, we have to find a solution for Windows -- which hopefully 
will work on the Unixes as well.
