Even at the ends of a spectrum, they remain imperfect and problematic constructs. When I said binary, I intended to continue to imply that they are as pointed out, said to be opposites on one semantic axis. This may have misled you as to my position, laid out in my previous parent^2 comment. At no point did I call them useless. to timwaagh below, if I had done the research to create coherent enough new constructs I'd be publishing a paper on them, rather than writing a chat answer.
