While I agree with your general sentiment about 3xx responses (often used to redirect example.com to www.example.com) I think your concerns about 8.8.8.8 are over-stated. 8.8.8.8 is deployed in many locations, which gives DNS-based geolocation a decent chance of working.
So in how many of the 196 or so extant countries does 8.8.8.8 resolve to a host which, when it sends a query up the chain, appears to be in the same country as the machine that made the original query?
How does a company know that another instance of 8.8.8.8 has been turned up or down or re-peered, causing a shift in the mapping of DNS queries to countries/ states?
