"Erlang style" supervision error handling is short-hand for opt-in, optional error handling without any compiler support. That's a pretty serious trade-off to not address directly.
What you describe sounds like a consequence of Erlang's dynamic type system, rather than its concurrency model. Besides, don't most languages have "opt-in" error handling? For example, I work mostly in C# and if you don't catch an exception, your program will crash. How is that different? At least in Erlang, my program might restart itself. Sadly that doesn't happen on most other platforms.
