exactly. It's user hostile to correct/undo the action. A 2 second drag-drop mistake requires the following to correct it: 1. realize mistake / stop-everything-you're-doing 2. reboot to recovery mode 3. change SIP setting --> disabled 4. reboot to normal OS 5. delete attribute you never wanted 6. reboot to Recovery again 7. re-enable SIP 8. reboot to normal OS and get back to work if you can remember what you were even doing 20 minutes ago. That's "user hostile" in my book.
