It's useful when checking binary packages from different minor versions. For example, we setup postgresql-14.0 and postgresql-14.1 aside (renaming one installation' directory and changing it's port) and perform the test. What've found with it was e.g. incompatibility due to linkage of different libicu versions (that was PgPro-only issue). I don't remember whether we found something related to PostgreSQL itself, but we definitely use this test and I'm not sure how to replace it in our setup with a TAP test. On the other hand, testing binaries is not accustomed in the community yet, so when such testing will be adopted, probably a brand new set of tests should emerge.
