DMs may upload to all suites, but only the highest version currently in
unstable, experimental or *-backports will be considered for DM-U-A.

If a package has architecture-specific packages or a buildd uploads only
architecture-dependant packages and there are also arch-indep packages,
the upload does not include all binaries from the Binary field.

Uploads that do not include source would trigger an exception when
remove is used.  discard does not raise an exception when the element
does not exist.
