Erm, what you do if the user saves his settings into the db, so you have 
one fixed value to work with? The use case of alternate defaults for 
variables is not clear to me. Bbut I have nothing against having that 
supported if you show a good use case, although we would need to hammer 
people to update their code to use hook_settings() as variable_get() 
will work as is without modification in Drupal 6.
