I thought of that, actually, but in this case we have content that is the same except visually very different on desktop and mobile, and so we had to change some of the markup to make that happen. The problem normally isn't noticeable, but if you have a page where you want that content to show on mobile but not on desktop it becomes a problem.
I was worried that moving it to the center would confuse our client. I think it's something that can be easily explained though, so it'll be okay. Would you let me know if you do change it, though?
