Just to be sure: You mean code to detect which packages have been
removed in the metadata? According to "repodiff --help", it might do the
job:
|    repodiff: take 2 or more repositories and return a list of added,
|    removed and changed packages.

So only the old metadata needs to be stored and then it could be
compared to the new one to get a list of packages that can be removed.
To get all packages that have been removed from updates-testing but do
not go into updates, because the update was unpushed, the list of
removed packages for the updates-testing repo could be compared with the
list of added packages for the updates repo.
