WP 3.3 > Still no option to enable automatic image overwrites?

I was really excited to see the new functionality with the media manager in WP 3.3 (specifically drag and drop uploads and automatic file type recognition)

But I was disheartened to see no relief in terms of the confusing manner in which WP continues to handle image overwrites (by appending a number to the image and creating a duplicate version).

Does anyone have a workaround that I can implement in my theme’s functions.php to enable automatic image overwrites, replacing the original image with the new one, and without changing the filename?

There’s another plugin out there worth checking out:

Enable Media Replace
This plugin allows you to replace a file in your media library by uploading a new file in its place. No more deleting, renaming and re-uploading files!
