Yeah, that's what I meant by best-effort only. Due to upstream Z3's design, without the binary, there is no easy way to retrieve the current installed version, so when I originally wrote the Z3 integration, it seemed fine to let the version check pass. Given the issues that have come up, it might make more sense to at least emit a warning, or explicitly fail if the version can't be determined, and prompt the user to install the binary.
