The goal of the series is a worthy one, but I would imagine people would
want to run these while on "maint":

    git cherry-pick master~2..master
    git cherry-pick master^ master

or even

    git cherry-pick -2 master

How about enumerating the commits with an equivalent of

    git rev-list --no-walk "$@"

as an alternative implementation?

The current behaviour would fall out just as a natural special case
because

    git rev-list --no-walk $commit == $commit

Hmm?
