Also happy to see the undo function include the footer now.
There are three concerns with the footer. First, it is auto-generated, and as best practice you shouldn't store auto-generated components in version control - especially components which often change. Second, it duplicates information found both in file metadata and (in greater detail) the version control log itself - this is more of a philosophical objection against denormalized data. Third, it will cause merge conflicts any time two users edit a spec concurrently - even if their edits are to completely different parts of the file.
