I would like to see TeX and emacs being optional.

I always recommend my friends to accept dselect defaults (i.e. standard
or higher packages) for a "first stage" or "first dselect pass", and
postpone the careful choice among 4000 packages for a second dselect pass.

If we downgrade such big packages to optional, the default dselect
install will be much faster.
