Well, this is a case where it can't work for one use case: Web surfing

Unfortunately, when you are dealing with a large number of websites  
implementing something wrong you reach a point where you have to decide if  
it is possible and realistic to work around the problem by detecting the  
existence of the problem, or drop the feature. For Content-Location  
working around it was not realistic.

Off-topic example: For HTTP pipelining we've implemented a lot of  
heuristics to handle bad servers, and there are still servers (from major  
vendors), that cause problems I'm currently unable to work around.

Not sure. The way I read it, it removes the one thing we were using it  
for: A Base URL replacement.

It may very well be that Content-Location can be useful in some  
applications, but ordinary web surfing is not such an application.
