The change itself looks fine; 👍 to that.

CI is failing a couple of tests - but if I'm reading it right, this an expected chicken-and-egg problem. This PR needs to point at the Briefcase OpenSuSE branch so that SuSE builds will complete, but that means the install tests fail version checks; but we need this PR in place before we can CI check the Open SuSE branch.

Have I got that right? We either need to accept these CI failures, or merge the OpenSuSE branch with no CI check? I'm fine with either - I just wanted to make sure I haven't missed something.

That's correct. And the Verify Briefcase jobs are failing because they bypass Briefcase-Repo and Briefcase-Ref altogether...
