Current thinking from the reviewer (Doug Rohrer, I know he’s on this list!) is that this head/match is now redundant, since the functions that call it check for use=true before calling new_key_epoch. So dialzyer is correct, the function only ever gets called with `true` now. Once again the age old refrain “never argue with dialyzer”. I hope that someone learned something so this thread wasn’t a complete waste of time.

Thanks, and thanks to all who replied.
