The "implicit fall-through for adjacent case labels" situation doesn't really exist, so there's no need for special handling in -Wimplicit-fallthrough. Labels apply to the following statement; when you have a list of labels with no intervening statements, every label in the list is associated with the same statement at the end, not the next label. You can never end up branching into the middle of a group of labels, so there is no fall-through.
