Well, "beta releases" never for one moment reminded me of my failures in dating or leadership.
But, to tangentially riff on your point, white straight cis males could never be recognized as even being capable of having such feelings, even if they had them. Only systematically oppressed peoples can feel that way, so it is said.
I believe for this experiment to be fair it requires an inborn, unalienable physical trait with particular cultural baggage that resonates with the negative connotation of the term. This combination isn’t that easy to come by, and might be hard to invent for those unaffected. “Beta” is unlikely to qualify (not unalienable); “master branch” maybe not (?); “blacklist” is debatable. Something involving country of origin/nationality/skin color might be it though (if the controversial cultural baggage condition is satisfied).
