Visual tweaks would be just visible to you. Most patrons just want to be able to customize what is visible to them anyway; very few do it because they want a fancy name to show off. But a button that lets you delete a comment for a limited time would at some point be visible to the user, and without checks in place server-side to make sure the timer is respected, someone could make an edit to the CSS to make that button always visible. If the button is clicked, it will delete the post; what should be done is not just make a button that hides itself after 10 minutes, but to make sure that you cannot delete your post after 10 minutes, whether the button is visible or not. Regarding your Administrator role comment, as stated, you would see that you're listed as Administrator, but you wouldn't actually be able to do Administrator things, and you would be the only one to see that role on yourself, ergo, it's only visual, and only visible to you.
