Only the first example is one that I’d call a full meta-conversation, to identify the problem to be solved and who should solve it. The others are meta in the sense that they’re about communication style rather than content, but not meta in terms of solving a more abstract problem, and it’s not helpful to mix the two kinds of meta.
I’m also not sure it’s actually taboo—it’s sometimes a little uncomfortable, but I don’t think you’d be shunned or expelled from a group if you tried to address the communication issues. You will find, in many casual groups, that some or all of the members PREFER this style, and you’ll need to decide whether to join in or leave (or put up with the annoyance of a non-preferred turn-taking protocol). But actually noticing and asking is both common and unpunished in most contexts I’ve seen.
