Definitely, though I have seen other solutions, like inserting non-printable characters in the problematic strings (e.g. "/etc/ho<b></b>sts" or whatever, you get the idea). And honestly that seems like a reasonable, if somewhat annoying, workaround to me that still retains the protections.

Another silly workaround would be to take a screenshot of “/etc/hosts” and use images instead. Would break text browsers/reading mode though.
