I doubt that "Positioning the minibuffer to the top of the frame" would
be "much easier": When Emacs enlarges the minibuffer window it then has
to move all windows beneath down by the number of lines the minibuffer
window has been enlarged.  To not make these windows' texts move down
accordingly (which would constitute a very unpleasent visual experience)
we would have to try to change these windows' start positions and
restore them accordingly when shrinking the minibuffer window back.
Obviously, with point near the top of the window or varying line heights
such an attempt might become very tricky or even impossible.

Putting the minibuffer window below some arbitrary (maybe even internal)
window of a frame would not run into such difficulties.
