I wouldn't go so far as to characterize it as a disagreement. In my
review, I only pointed out that this series was introducing some new
instances of inconsistency which some earlier efforts (started by
Michael Haggerty) had eliminated. As mentioned in [2], I personally
prefer the term "worktree".
These two words mean different things, so I am not sure there is
much room for personal preference. If what a documentation refers
to is the working tree plus its administrative files, referring to
the whole as a "worktree" would be more precise and concise. If the
discussion is only about the thing above .git/ that the editors and
the compilers see, "working tree" is the right term to use.
