DORA, recently, has been moving towards its own sphere outside of DevOps, hence why the acronym isn't usually expanded. So many of the core principles of DevOps (communication, collaboration, working across teams, etc) have impact beyond the DevOps discipline. DORA has been venturing into platform, DevEx, AI, etc.

From last year's DORA report:

"We are committed to the fundamental principles that have always been a part of the DevOps movement: culture, collaboration, automation, learning, and using technology to achieve business goals. Our community and research benefit from the perspectives of diverse roles, including people who might not associate with the "DevOps" label. You should expect to see the term "DevOps" moving out of the spotlight."

I was confused, since DORA is also the EU Digital Operational Resilience Act.
