Comment (by chessai):

 I am opposed to this. I see no benefit, and agree with most of the
 criticism posted on reddit. Users of -Werror typically have the mindset
 that they want warningless code - because whichever warning flags they
 have enabled in tandem with -Werror are serving as guards against poor
 code. If they don't have this mindset, then I don't understand why they'd
 use -Werror. Deprecations happen, and things will break because of it. I
 don't agree with the lounging about on the issue on unordered-containers
 you mention because of breaking -Werror builds (I think anyone using
 -Werror ought to care enough to adapt to deprecations!), but I also don't
 think there should be any exceptions to -Werror.
