Possibly, but not anymore. I believe the diff should have been applied to
nav menu items, not attachments.

That said, can_export only affected the UI in 3.0. Attachments that have a
post or a page as a parent do work as before. Attachments without a parent
should also be included in the export -- can_export has no effect on the
export file creation.

Jon (duck_) can probably go into more detail on the changes in 3.1, but
you'll want to look at http://core.trac.wordpress.org/ticket/15197. A good
amount of this has changed in trunk, to say the least.
