Everything you wrote is not very interesting or relevant story we
want to see in order to explain and justify this change.  The title
itself is sufficient, i.e. it had poor visibility, and you fix it by
giving it better visibility.

A more relevant is why you needed to find out what the former should
be in the first place.  "git submodule init" and "git worktree add"
would create them as necessary without you needing to know about the
exact implementation.

Do not unnecessary rewrap existing text, only to insert a few words,
to force reviewers read a lot more than needed.

Running "git grep linkgit:gitrepository-layout" would help you find
the right way to spell this one, I think.

Thanks.
