Sooner than later? Release data planned? This could be REALLY REALLY useful. I just imported about 30 redirects for a particular campaign I'm running and a character in the redirected URL was wrong... had to dlete them all and add back in bulk.
WARNING: it doesn't stop by itself! You have to reload the page to stop the script. But you can run it straight from the javascript console in every browser.
If there is some commonality with the redirect URLs you want to delete, you can now delete 10 at a time, by searching for the common string and using the select all tick box and then clicking delete.
Not perfect, but a great start and a timesaver compared to how it was before.
