There are an unbelievable number of use cases for forwarding X. Even the web browser example you gave - perhaps I don't know how to tunnel my IP traffic (but srsly, ssh makes it easy) and i want to modify my routes at home....it's painless to just tunnel X for kicks.
Granted, most people that know how to do one can do the other, but it's extremely useful and I will be sad to see such an architecture go, if it goes out of common use. X is great.
