Also remember we are talking about *stable branches* here. The only
acceptable things there are bugfix backports and CVE fixes. So:

- there is no case of partially-merged features that span multiple CRs
- in the rare case of a bugfix needing multiple commits, those should be
squashed in the stable branch
- if the fix is so huge that it can't be merged as a single patch, it's
probably not desirable in the stable branch

The stable branch should always be usable and releaseable. If it's not,
you're doing it wrong.
