What needs to be patched? If you do something incorrectly it's not a bug. As .m. said, the settings.php file (which is only a cache file, how do you think it'd be able to detect changes on upload and update database automatically?) and then the same settings in ACP need to be edited, in this correct order. That's all, most people don't have a problem with that.
Not to mention that you could have changed these settings in ACP before moving, if you knew the new domain.
