Has this cow ever written anything noteworthy or been a key contributor to any project whatsoever?
Yes,
quite substantially. This is a programmer who turned into a tranny, not vice versa.
What a bizarre hangup and odd thing to push- a handful of paragraphs of dumb garbage to "protect" the arbitrarily decided disenfranchised in what should be meritocratic groups. I doubt any of the actual contributors give a shit if literal Hitler was coding for them if he was good at it and leave anti-Semitic comments every other line.
Kinda. (heh, and I assume you mean to say that Hitler isn't leaving anti-Semitic comments)
The tech world has a lot of pretty liberal people. They're interested in diversity and they're for encouraging minorities to get into open source software and stuff like that. I think that's a good thing, when done right.
Additionally, there are a bunch of nerds who are extremely against any restrictions on their behavior, even on-project.
Linus Torvalds comes to mind. He chimps out a lot. He's kinda like Gordon Ramsay, except that most cooks aren't autistic enough to see Gordon's tantrums as guides for their own behavior. Programmers on the other hand...
So some set of rules for how to behave on a project (could be as simple as "don't be a dick" for smaller projects, but perhaps more explicit rules for larger projects), are definitely useful.
The key is that you don't let SJWs write those rules.
The problem with the CoC is that it will be used to formalize these bizarre SJW witchhunts. We've seen Coraline herself try to pull this shit. Coraline intended for this to be used as a weapon.
Coraline could still have a solid career as a programmer. But if she can land a well paying gig as diversity officer sitting on her ass and just sperging about pronouns 24/7, why not? (Of course, we've since learned that that's a big "if".)
