Using thread_local on iOS requires iOS 9 or greater. Chrome for iOS now requires 13, Skia sets the minimum to 11 for test builds, and Flutter actively does not support 8 or earlier. Dropping support for iOS 8 in practice and moving to iOS 9 makes it possible to use thread_local without reservations on iOS.
