A bit of a nit, but "Document..." implies no functional changes, but you are
changing the physical structure. This can have negative consequences in some
cases, even if the removed field is unused.

Someone reading through the git history might skip over patches starting with
"Document..." when looking for change which impacted behavior.

Again, for future submissions.
