If CI hasn't evaluated the branch yet, then updating tzdata (yet again,
to 2021e) shouldn't require extra rebuilding when the time comes to
actually build the branch with Cuirass. The same number of packages will
need to be built whether we use the current tzdata release or an older
release. Or do I misunderstand your objection?
