We have no tickets about the previous problem to study?

rev-upgrade only checks library linkage. If you're saying that this software links with a library inside Xcode, and that the install name of that library varies by Xcode version such that the software linked with the library in one version of Xcode fails with a library file not found error when Xcode is upgraded to a new version, then yes rev-upgrade would detect that. Otherwise, no it would not.
