 > This won't be possible, since it will clear all subdomains (and the
 domain itself), not just the current (sub)domain - not only will this
 massively worsen usability (since the whole cache is cleared incl. JS/CSS
 and media (!) it will result in significantly more traffic for large blog
 operators.

 Then it seems like this would only be feasible to enable by default for
 non-multisite installs.
