How people feel about generally not having += on long strings in stdlib (since the refcount = 1 thing is a hack)?
Sometimes the use of += for strings or bytes is appropriate. For example, I deliberately used += for bytes instead b''.join() (note that there is even no such hack for bytes) in zipfile module where in most cases one of component is empty, and the concatenation of nonempty components only happens once. b''.join() was noticeably slower here.
