AsyncThrowingStream.init(unfolding:) has no onCancel parameter

I just noticed a discrepancy in the AsyncStream APIs:

AsyncStream has an init(unfolding:onCancel:) initializer
- The onCancel parameter is optional because it has a default argument = nil.
AsyncThrowingStream only has init(unfolding:) without the onCancel parameter.

The proposal SE-0314: AsyncStream and AsyncThrowingStream proposes the init(unfolding:onCancel:) variant for both stream types, so not having it on AsyncThrowingStream looks like an oversight?

Sounds like an omission, please file an issue on GitHub - swiftlang/swift: The Swift Programming Language please?
