Ceryle think of it this way.

That lock is taken off, and some asshole spams "I coming" on 20 images. Guess who gets to clean it all up. While I do agree the limit should be raised a few, but say it still should stay. I know how frustrating it can be, I wasn't a mod when I first joined, so I just worked around it, by waiting or editing a comment.

Like I said in the other thread member accounts only have that lock, so if you do something to get a upgrade in status, then that lock will go away. The fastest way is to donate, or work you ass off like I did. 300 tag changes a day is what got me privileged account.
