The OttavaBracket print callback predates the new(ish) line-spanner code.

It's perfectly possible to use ly:line-spanner::print, but it's not
really suited to rendering brackets: you have to add the bracket tips
as markup, which makes it difficult to change their direction
automatically.

\relative c'' {
  \override Staff.OttavaBracket #'stencil = #ly:line-spanner::print
  \override Staff.OttavaBracket #'bound-details =
    #`((left . ((Y . 0)
                (attach-dir . ,LEFT)
                (padding . 0)
                (stencil-align-dir-y . ,CENTER)))
       (right . ((Y . 0)
                 (padding . 0)
                 (attach-dir . ,RIGHT)
                 ;; ideally, draw-line should support dashed lines
                 (text . ,(make-draw-line-markup (cons 0 -1.2))))))
  \override Staff.OttavaBracket #'left-bound-info =
     #ly:line-spanner::calc-left-bound-info-and-text
  \override Staff.OttavaBracket #'right-bound-info =
     #ly:line-spanner::calc-right-bound-info
  \ottava #1
