If a stream or stream_view object is const, it becomes useless, as no methods will be allowed. This came up in GENE where there is a helper class which has const methods that use a stream member variable, and because the methods are const, this becomes const and the stream member becomes const, and it breaks. It's not obvious what the correct change is here - should stream methods be allowed on const, or should GENE be changed to make those methods non-const.
