Yaron, I read over the conversation and would like to posit the question in a different way.

Some corporate person, for example, downloading my software, could see that file and think that they're bound by the Code of Conduct when sending me a patch, when in fact (for better or worse) they're not.

If the patch is submitted to a Wikimedia technical space (Gerrit) then the submitter would be expected to follow the community expectations outlined in the Code of Conduct. This, in my opinion, is a benefit to you and other extension contributors. The CoC says (paraphrasing), if you want to participate, great. We do have some things that are considered unacceptable behavior. We include mention of this in visible locations where it makes sense so folks are aware.

This should deter most well-reasoned folks from letting the worst of themselves get the best of them. For those that persist in ignorance of the expectations of the community, we can show them the door.

This keeps you, and any other individual contributor, from having to figure out how to respond to anyone being a jerk new again each and every time. It sets clear expectations for new members of our community on how we treat each other.

So, the question I would put to you or anyone asking "Why do I have to have this here?" would be, "Does having the Code of Conduct make my work in this space easier and more productive?"

In my opinion, yes. Please take a moment and consider this before deleting anything.

Yours, Chris Koerner clkoerner.com
