Depending on how the uploads happen, they can remain readable by other
DDs for a short while (see the bugs mentioned in the announcement).  But
this might be less bad than uploading via unencrypted ftp.

DDs can also see which packages were uploaded as debianqueue's logs are
readable by local users, but I believe this shouldn't be too large of a
