Indeed. I think though that at this point this is well enough understood 
that it's not really worth changing the API -- people will have to support 
the old one for years anyway.

Well, the DOM storage API and the SQL APIs provide a better API than 
cookies, but of course that data isn't sent over the network. A library 
could be made to interface them, though.
