Thanks for the interesting NHSX link. A reaction.
There may be some jobs for which anything other than pure merit is remotely relevant. Things like flying airplanes (aeroplanes?), preforming surgery, building cranes or hospitals, or research in physics or mathematics aren't among them. Positive, negative or any form of social-engineering discrimination would be, er, frowned upon.
Maybe appearing on the television or in parliament would rule out the Joseph Merricks amongst us. I'd put spending taxpayers money in the first category. JM, or someone identifying as a green wheely-bin would be fine if he or she or it truly understood what they were doing, and I'd hope (close to desperately) the interview panel would focus exclusively on that.
On the Boeing website (I think it is still there), the first thing you see is that there are 42 diversity councils in Boeing. Excellent. Tickety box. There didn't seem to be an awful lot of clued up folk, or wheely-bins reviewing the design of their airplanes (aeroplanes?), or at least being listened to.
