Thanks Linus, this is helpful. Andy and I have updated our tooling to
reflect the above, and we will modify our human-information-add as
follows:

The pull-request body will include merge-specific information and
instructions which are unrelated to the content. e.g. previously merged
fixes, pre-merged immutable branches, recommended merge conflict
resolution.

The tag message will include a human written highlights and summary,
followed by a git shortlog grouped by driver with a prefix indicating it
is automatically generated (although we will still verify the script
grouped things properly). This just offers a quick glance at what
changed by driver. I will also sometimes group fixes from static
analysis that would otherwise be rather noisy under a common group, e.g.

sparse fixes:
- Updated several drivers to use const strings
