There's no real structured concurrency replacement for Lock, Stream, or Port, so are there plans to introduce new capabilities in Foundation, or shift things down to the standard library?
Codable isn't equivalent to NSCoding, is there a plan for enhancements here? Will we be getting Codable improvements to remove its various bottlenecks?
What about URLProtocol? This is a rather archaic, if powerful, type I'd be happy to replace with something better but sad to lose its capabilities.
What about background URLSession support? Will that remain an Apple-internal capability?
Does this give us the opportunity to rebuild URLSession using common types that can be shared among the community (HTTPHeader, etc.)?
Can this version of Foundation have external dependencies on non Apple frameworks, even while it uses swift-algorithms or other Apple-authored dependencies?
