It's necessary everywhere we interface with C APIs and binary formats that use them. Even the stdlib is full of candidates--the flags in os, stat, etc. are all bitmasks.
I could see arguing that these shouldn't be considered the same kind of thing as an enum, or are too complex to handle in what should be a simple enum library. But I can't see how you can say we don't need them. The situation is identical to ordered named int--same status quo, same downsides to the status quo, etc.--except for the implementation complexity.
