I gratefully accept the information of your post, but I don't think it manages to make the intended point. Notice how many times you used the word "should", which was never a consideration in my post.

We could talk about should. As a starting point, it would seem to me most useful to preserve meaningful distinctions which convey information, and otherwise make language as fluid and relaxed as possible. But I'm not expert.
