That's not the problem though. The branches generally being too far
apart atm is. The single cherry-pick won't solve that. Applying these
patches to one tree just adds a dependency that will not be around in
the topic branch baseline, creating a new problem for merging the topic

The cycle in review -> apply to topic branch -> merge topic branch just
needs to be short enough. We can't have the topic branch laying around
for more than maybe a few days, or we'll have problems.
