Doesn't this need a clear call-out in the text to highlight the
distinction, so that it is obvious at first glance to the casual reader?

I'd ended up with something like:
- worktree
    A directory whose files and sub-directories are (selectively) under
Git revision management.
- working tree
    The working tree comprises Git revision management meta-data for the
worktree,
     and the worktree itself.
    The meta-data may be independently located away from the worktree's
data.

The key feature is to have a layout structure that shows the distinction.

Or are we trying to remove all references to "working tree"? Or have I
misunderstood?

Are we removing the above "working trees" phrases as well?
