Not quite: once 5.x+1 is *released*, 5.x (if not LTS) is closed
(unless we have a pressing reason to release another 5.x.y).
So, in the interval between 5.x+1 branching and releasing,
we have three branches.

Indeed.

We switch to cherry-picking into 5.12 when 5.14 is created.
See QUIP-5,

So creation of 5.14 switches our merge pattern from 5.12->5.13->dev
to 5.13->5.14->dev and the 5.14 release (probably) closes 5.13.
Again, we could of course change that.
