I prefer they working on making the game run smooth and bug free. All the things that annoy people are not exactly bugs, they are just design choices.
I personally hate the whole inbreed messaging. Get rid of that message, I already knew they were father and daughter. I keep an eye on everything that happens in my zoo, and wished that I could switch things off that I already knew that would happen but doesn't bother me. They are animals, not humans.
I feel compelled to point out that the inbreeding messages are not exactly a bug, either, and are exactly the same thing as the heat map popping up every time we place an education item.
But I agree 100% with both the inbreeding messages and the heat map popping up constantly being seriously annoying.
I also agree 100% that I would like them to work on making the game run smoothly and bug free, but I think that is already what they are doing. Nothing should stop anyone from reporting annoyances like the heat maps and the inbreeding messages, as the devs can just add them to their "to do list" and get to it when they have time. So I don't think there's any reason to discourage people from reporting these annoyances.
