The issue there is then you have to properly determine what packages
to remove from the repo (unless you just keep everything, which has its
own problems); in this case, recomputing actually makes the code simpler.

While that would make things simpler and shorter, I doubt it's really
practical. Enough people use and want multilib that I don't think we can
just unilaterally remove it. Moreover, the multilib portion of the compose isn't
the primary time eater.

I certianly don't want to go back to the whitelist case where every time
someone needed a new multilib package we had to update a static whitelist
in the update push tool. That's just silly.
