Comment 1 for bug 55209

Right, to simplify all wierdness related to UploadPolicy.announcelist and DistroRelease.changeslist would be definately acceptable to have "changeslist" as a required attribute when adding a new distrorelase.

Otherwise, we could let "changeslist" as an optional attribute and include subtasks in the planned "Upload Policy Redesign" major task, to fix IDistroRelease, modify UploadPolicy.announce_list and other bits in NascentUpload.

Personally, the former would be cheaper and faster, for now.
