FWIW, I always use "checkout -B" at least twice during an
integration cycle.  "git checkout -B jch master" before rebuilding
my private edition with select topics (including all the topics
already in 'next'), plus "git checkout -B pu jch" before rebuilding
the 'pu' branch with the other topics I happen to have looked at.
These are similar to your use case---the branches have constant
"purpose" and always exist, but they are rebuilt from scratch when
they get updated.
