Asset Processor and v2 Turnitin integration

The https://community.d2l.com/brightspace/kb/articles/33012-september-2025-20-25-09#lti-asset-processor-service-integration-in-assignments-new Release notes section about "LTI - Asset Processor service integration in Assignments" mentions instructors will have the option to "Add External Tool" in the "Evaluation and Feedback" panel in Assignments.

I can see this live on our development (sandbox) site since it was updated earlier this month, but I'm a little unsure what this is going to look like on our productions site because we don't have Turnitin v2 and 1.3 enabled on our development site whereas we do on our production site. Since the release notes say "slight impact" only, rather than high impact, does this mean that our v2 integration will still be in place? I.e., the option to enable/disable Turnitin will appear either above or below the new "External tools" bit?

I found the documentation about Asset Processor https://community.d2l.com/brightspace/kb/articles/33083-asset-processor-for-assignments-services-extension-with-lti-1-3 but there's no mention of Turnitin.

I checked turnitin.com, and there's no obvious mention of v2 no longer being supported... or any mention of D2L's Asset Processor.
