If only power users are expected to install packages that require unauthenticated packages as dependencies, perhaps those packages should not be listed in the Ubuntu Software Center to begin with.
For example, if you try to install ubuntu-restricted-extras through software-center, then you get a warning about w32codecs not being able to be authenticated. Great. Why is ubuntu-restricted-extras listed in the Software Center at all, then?
Anything listed in the Software Center should be installable through the Software Center. Anything not installable through the Software Center shouldn't be listed there.
