No, it is not.  Those are pretty broad use cases.  I want to see them 
more specifically defined.  e.g.  "correlate the ownership of websites 
in different languages" is still pretty broad.  WHO do you want to do 
the correlation?  (Which pieces of code?)  Is this for statistics and 
analysis (only) - e.g. so the Alexa list reflects the aggregate of 
correlated sites?  Or do you want client code doing something?  Do you 
want cookies shared?  Credentials?  I realize that this could touch 
many parts of the stack.

Put another way, if you're right that:

Then the use case(s) needs to be very clear.
