While it makes sense to see Java coroutine as Thread, it makes less sense to see generators as Thread. So if we introduce generators, we will use a different mechanism than virtual threads, so the expectations are not the same, so most of the spooky issues discuss here do not exist.
We are getting a bit off topic but we can't be too dismissive of the spooky issues that would go with the control flow of generators. Even if implemented on delimited continuations, and even if thread confined, there are a bunch of related to reachability and breaking structure. There's enough there to keep a market for Ghostbuster proton packs going for a few years.
