For the record: I don't mind whether the major mode is first or last,
nor whether it is Initially shown expanded or collapsed.

The difference is twofold, IMO:

  . it presents a UI that's familiar to most users
  . it makes it easy to show initially a very short text without
    hampering user's ability to get to the information she needs most

If that's not worth the trouble, then what is?

(In case it wasn't clear, I wasn't suggesting that we make this change
before Emacs 23.1 is released.)
