Exception handling is seldom used in the large except to void the exception.

And then only near or at a top-level event loop.

Exception handling is the issue here, because of the proposal to add reifed break and continue as thrown exceptions. How exception handling is practiced (usually not) is highly relevant.

Wishing for JS users to happily add more exception handling won't make that work happen, because it costs a lot. That it costs a lot (too much in my view) is enough to consider not adding new exceptions that must be considered when designing all "looping" and "wrapping" (AOP) APis.
