I haven't had a chance yet to look at Jacob's v3, but this series does
close a gap in worktree usability[*], and v3 addresses a stated
concern of mine against earlier iterations, so I think a "negative
lean" may not be warranted.

[*] In particular, it is currently impossible to create a worktree
from a brand new bare repository:

    % git init --bare foo.git
    % git -C foo.git worktree add -b main bar
    Preparing worktree (new branch 'main')
    fatal: not a valid object name: 'HEAD'
    %

whereas, with this patch series:

    % git init --bare foo.git
    % git -C foo.git worktree add --orphan main bar
    Preparing worktree (new branch 'main')
    %

(The commit message can probably be improved to spell this out since
it wasn't obvious to me, simply from reading the commit message, that
this problem existed.)
