        The “problem” as I see it is that we have at least two groups of
        VC users, – those who’d use vc-root vc-dir buffers so often as
        to make prompting an obstacle, /and/ those who’d prefer for
        vc-dir to remain consistent with the likes of find-file in its
        use of default-directory as, well, the default.

        FTR, one another case where such an “inconsistent” behavior was
        implemented at some point is desktop-read.  However, this change
        is easy to revert with an explicit (setq desktop-path '(".")) in
        one’s ~/.emacs.

        I believe it would be nice to offer the “pro-consistency” VC
        users a similarly simple way to revert to the pre-f302475471df
        behavior.

        (Personally, I guess I’d simply revert the change locally,
        should no suitable customization be implemented.)

        TIA.
