Even when thread confined, the main concern has been that exotic control flow yields leads to surprising behavior with many of the existing constructs, e.g. in your example think about behavior with finally blocks, try-with-resources, locks, ... when the iterator is not fully consumed.

Hmm, yes, I was thinking of doing something very much like this myself,
so I'm glad I saw your reply.

Even while the iterator is still running, there are still some potential
surprises. I wonder if, whatever we do, any form of coroutine will need to
have its own identity as an instance of Thread.
