Well, I don't see how you can "easily" reproduce a build of an "old" version of a package without re-bootstrapping the whole old state of the repository to build against. I understand that we eventually have enough information in the package to actually re-create that repository "soruce" state and we keep old sources around but not binaries.
Depends on whether one wants to reproduce some Tumbleweed package from a random point in the past or one from a released distribution. For the latter we do keep binaries of released maintenance updates. Nevertheless it should be possible to reproduce binaries in any case, even though it might require some time and computing power.
