I'll be looking forward to this . . .

Well, it's a habit.  I've made a conscience decision to not use
show_all().  It's nice, but I'll often discover a need to have a
couple of widgets hidden on startup.

I just find it more maintainable to put in all the show() calls while
the layout is still fresh in my head.  It's just a little protection
against a possible future burden of adding a hidden widget to a
complicated layout.  I wouldn't expect most people to agree with that
logic though, and you're right, it doesn't make much sense for this
example.
