Fair enough, there seem to (still) be attraction to it, so committed in
r1738878, let's see what others say...

I can grok the "isolation" argument (prevent requests from reaching unexpected
services), but not the security one.
This is definitively not a security feature (like SSLv2 isn't anymore), and
shouldn't be presented as such.
As I said earlier, either localhost is trusted or it is not, and in the latter
case "secret" won't change anything (significantly).

This is called "authentification" in crypto, not blah, and it's probably the
only way to achieve security goals, if any...
