I'm not advocating committing secrets to version control.

But you can learn to phrase your WTFs about your colleague's code politely and constructively. I would even argue that this an absolutely basic skill for professionals. It typically leads to faster and better answers whenever a discussion arises.

Even if confusion seems to spread in a discussion, I would expect the person who realizes this first to call that out and and to reset the conversation.

There is nothing magic or onerous about this.
