That's the easy case.

This case depends:
- historically, it has obeyed special-display-*, which would mean it
  should obey d-b-alist as well.  Hence the ACTION argument.
- even if/when we want to change C-x 5 b to override the d-b-alist (and
  special-display-* as well, of course), there are several other
  `other-window' cases where it's not nearly as clear cut that the
  user really meant to override d-b-alist (e.g. because it's the only
  command that has a convenient key binding).

Also you forgot the switch-to-buffer case, which uses the
ACTION argument.
