Every six months between mass branching of the next Fedora release and the updates-testing enablement, there's a lot of packages that don't get submitted properly for the branched release. In the past, when I reported bugs about these missing updates, packagers had usually just missed the "updates-testing enabled" announcement, or were not aware that they needed to file bodhi updates at all.

It would be great if the "fedpkg build" command would print some information about this after a successful build, something like "do not forget to submit an update for this build, otherwise it will disappear into the void and not get pushed to package repositories".

It should be possible to determine whether to print this big red warning based on the build target. The only two build targets for which no updates need to be manually crated are "rawhide" and whatever "branched" means (but only between mass branching and updates-testing enablement). For all other targets, creating an update manually (either with "fedpkg update" or by using the bodhi web UI) is necessary.
