@Dennis would you know if there was any kind of potential plan to support the ability for a testTarget (from a package) to support opting-out of parallel testing across the target? I understand that we are planning to add support for suites (and individual tests) to opt-out of parallel testing… but would there also be an ability to force that preference across the whole target (which would then have precedence over the shouldRunInParallel flag passed at command-line)?
