feature request: make the "comments closed" text optional on all themes

So, I'm trying to spread the word that wordpress is a full fledged cms and isn't just for blogging. However, almost every theme I've tried has some sort of "comments closed" text, even for pages (rather than posts). This make sense for a blog, but doesn't make sense at all for a 'regular' website.

I can easily remove this from the themes, but it would be nice if all the wpmudev themes had an option that controlled whether or not to highlight the fact that comments are closed.
