I’d also like to note that this list can be invaluable when rebasing
commits and resolving conflicts.  It’s not strictly necessary (just like
other parts of a version control workflow are not strictly necessary),
but it can serve as a sanity check in a time when the diff is not
authoritative as it is in flux.

An explanation as to why things were done is also very useful in those
cases, but an overview on the *conceptual* changes at the procedure
level (rather than the plain diff that’s only concerned with lines and
not with the context in which the changes occurred) provides additional
valuable information that the commit diff itself cannot provide.

You can, of coures, browse the code with the diff applied and without
and see the full context in which those lines were changed, but even
with a nice interface like the one magit provides that’s much more work
than looking at the commit summary.
