Rather I think what we should wish for is that they be unnecessary, or at least it be unnecessary for them to be as fleshed out as they are. I’ve found a lot of FOSS communities to be quite casually misogynistic—you could just say to ignore it and focus on the code, but it most certainly makes it harder to focus on the code when the community is subtly hostile towards you. If you think CoCs are unnecessary even for large projects then it’s probably because you’re not one of the demographics affected by the problems that led to CoCs proliferating. Once a project has enough of a community around it I think a CoC is reasonable enough in the current culture.
