I'm surprised that no one has mentioned so far that there was a previous, exhaustive, discussion of this question on github:
https://github.com/mozilla/rust/issues/2643 As far as I can tell, this thread adds nothing new that wasn't already discussed in the comments on #2643. So that strongly suggests to me that nothing needs to be changed.
