I don't see a reason to do that.  If we could distinguish actually
problematic cases from safe cases, it would be helpful, but we can't.

Moreover, throwing a warning would encourage people to do actively
*unsafe* things to suppress the warning --- like marking functions
as immutable when they really aren't.
