For removed symbols, bringing back the ones that are still needed is easy. But what do we do with the default-FOO variables, once the machinery for their generation is removed? In any case, this needs a NEWS entry listing all the removed variables. > The parts for buffer_defaults is incomplete of course, there are many > references to this structure.

Once it is not exposed to Lisp as variables, what's the harm? Thanks.
