It is weird. I think both actors and the upcoming ownership model (for Swift 6.0) are important. But they are huge to consume with (hard to understand, big foot-print in compiler).

Maybe at some point, we can have Swift 7.0 which demotes classes to a special type of struct (you cannot without ownership model) like Arc in Rust, and that can get rid of some bloats.

I see two issues when the language evolves: 1. the type system still needs some work, parameterized extensions and non-existential / existential type differences are the two major issue I have. 2. get rid of Foundation on non-Apple platforms. The community should really say Swift 7.0 is the "done" version like Go 1.0 (or Julia 1.0), and we will do fixes, small type system QoL improvements and improve standard libraries and have no plan for 8.0 any time soon.
