From the Agenda summary:

Management Council. The Council approved sponsorship of 2022 NCAA convention legislation to add STUNT as an emerging sport for women. The Council noted the continued growth in high school STUNT sponsorship and participation, steady increase in the number of member institutions sponsoring STUNT, and support from the sport’s national governing body as compelling rationale to include STUNT as an emerging sport for women.
