A small few cherry-picked commits are easy to manage in each release candidate cycle. It's the hundreds of cherry-picks over 5 months, some of which were modified during the cherry-pick process, that makes maintaining a non-divergent master a challenge.... right now master and integration are 5 months apart on a genuine merge-base.

In essence the master reference "post-it note" just moves along integration's history to the latest snapshot tag in an ideal world of no cherry-picking at all. Going through the release candidate hoopla just gives us the opportunity to bug fix (with more recent integration commit "essential" cherry-picking or otherwise).

I'm comfortable with that - sounds just like my work!! What are tests?

Let's keep it easy for Wonder "users" and those less familiar with the layout.
