This isn't new to the approval nodelet; you could always do it from the section pages, provided you had attained the sufficient level. But anyway, I don't think it's a problem. The major intent of the approval system is to prevent badly formatted, misphrased, or obvious questions from reaching the front and section pages. Monks experienced enough to approve nodes (i.e. level 6+) should be knowledgable enough about the site and Perl in general to avoid these problems. Of course, were someone to start posting spam and approving it, a change would be needed. But until that happens, I think we should give higher Monks the benefit of the doubt.
