Is not it the same as we do now?

box.load_cfg
  apply_default_modules_cfg
    log.box_api.cfg_apply_default(cfg)

box.reload_cfg
  update_modules_cfg
    log.box_api.cfg_update

The thing is that if we create some kind of geneal callbacks
we need to provide that named "stages" and hook-in modules
when they're loaded in.

If you have some other code in mind please show it as a pseudocode
