Yes, because you are inviting attention to your site in a way that does not serve any real purpose. Unless you are specifically sharing configurations which others may find useful, the only likely result is increasing the visibility of your site to crackers and bots (regardless of whether your configuration itself is problematic).
Of course, as pehrs points out, if your configuration has an identified vulnerability, you are exposing it to automated attacks. While "security through obscurity" is often derided and sometimes abused, it is a component in your overall security (like window shades). And while encrypting it might offset this danger, it would be better just to avoid it entirely.
Generally speaking, you shouldn't expose any information about any system without a specific purpose in doing so.
