Uh, that's kind of wrong. How would a <Layout> element work if the XML
file would not be walked from top to the bottom? How would
<Include>/<Exclude> elements work? XML elements are parsed in order.

Anyway, menu items are not XML at all. They're just files spread over
several directories and - as we all know - there's no way to e.g.
switch two file "positions".

See above. Keeping the XML node order is not the problem.
