In contrast a debug build would check and report them even if verification were disabled. To make it easier for developers testing in product mode predominantly we changed the behaviour so that these constraints are always checked and reported. The intent was for product builds to run faster by skipping the checks, but in practice that doesn't happen - see bug report for background details.
