This looks like the recently added outline-default-rules
(that also can be used for diff-mode outlines, but not for diff-refine)
with such possible values:

  - `subtree-has-long-lines' to only show the heading branches when
    long lines are detected in its subtree (see
    `outline-default-long-line' for the definition of long lines).

  - `subtree-is-long' to only show the heading branches when its
    subtree contains more than `outline-default-line-count' lines.
