Entirely possible that this is what I remembered.  However, the
responsible commit turns out to be a good match to my vague recollection
regarding content, commit message, date and author:

commit 2f4f92007956983e6f5cb5136a57ddaa0cd9428e
Author: Eric S. Raymond <address@hidden>
Date:   Mon Dec 1 06:23:10 2014 -0500

    VC API simplification: remove ability to set initial revision.
    This hasn't made any sense since RCS, and was a dumb stunt then.
    * vc/vc.el and all backends: API simplification; init-revision is
    gone, and vc-registered functions no longer take an initial-revision

and so my comments regarding the likely reaction to a wish for
resurrection of that feature are probably not wide off the mark.
