We're also relying on this on Xcode 12 so if it's no longer supported it will be a big blocked for us. Not all dependencies work yet on M1 so this seems necessary. https://github.com/braintree/braintree_ios/issues/564

This still seems to be a problem. Tried with an Xcode project macos command line tool template, and with a SPM exectuable target. Both show empty concurrency instruments but the time profiler is fine.
