Removing obsolete stuff is an ungrateful job, as we need to brace for
complaints and have a Plan B for if/when they need to be brought back.
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.

Why do we need to remove buffer_defaults?  Once it is not exposed to
Lisp as variables, what's the harm?

Thanks.
