  i do see the following snippet in bisect_next_check():

  bisect_next_check() {

  ... snip ...

        case "$missing_good,$missing_bad,$1" in
        ,,*)
                : have both $TERM_GOOD and $TERM_BAD - ok
                ;;
        *,)
                # do not have both but not asked to fail - just report.
                false
                ;;
        t,,"$TERM_GOOD")
                # have bad (or new) but not good (or old).  we could bisect although
                # this is less optimum.
                eval_gettextln "Warning: bisecting only with a \$TERM_BAD commit." >&2

  ... snip ...

so i guess it's possible.
