I meant intranets where the web designer can talk to the administrators who can flip a central switch to make all clients opt-in to experimental features. 

I hate to admit it, but “controlled” also applies to global non-Web scenarios that employ CSS and provide dedicated proprietary consumer applications, e.g. Apple’s .itlp (iTunes LP) or .ibooks.
