IMHO this is best-practice anyhow.. For example: https://lore.kernel.org/kvm/20220224142024.147653-1-yishaih@nvidia.com/ Which is perhaps a strong case for including meaningful cover letters like the above as a merge commit - but git needs some easier tooling to show the cover when starting from a commit id: 'git show --cover ' With b4 having the range-diff functionality it also allows reviewers an easier way to generate their own diffs between versions of the series, and allows people splunking in the git history to discover the entire conversation and all prior versions (Konstantin, it would be nice if 'b4 diff' would take a pair of lore URLs) Unfortunately it is a bit of a PITA for the submitter so not too many people seem to do it.
