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.

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
