If at some point in the future we have another transition as extensive as time64, then libgtk-3-0t64 could conceivably be replaced by some other package, which I have modelled here as libgtk-3-0xyz. If that happens, we need to avoid deletion of immmodules.cache, otherwise we will have another bug similar to #1065494. This test-case depends on several implementation details of dpkg-repack and libgtk-3-0t64, so it might need to be adjusted in the future. As a result, I have marked it as flaky, so that failures in the official autopkgtest environment will not be considered a release-critical bug that stalls migration and requires immediate intervention by maintainers.
