Right now UW throws an error on the last step if a file with the same name (!) was previously deleted. The error message is: "There was a file by this name, (...), but it was deleted and you can not reupload the file. If your file is different, try renaming it." This is just user-hostile and unnecessary, getting into the way of the user just as they're about to wrap up the upload. It's useful to detect and block files with previously deleted contents (!), but a previously deleted name should be quietly ignored (and is indeed quietly ignored by the old upload form), instead of being a blocking error. We already have the blacklist and many other error conditions so I think we can safely get rid of this one.
Was this the patch you had in mind? https://gerrit.wikimedia.org/r/8728
