To be honest, and this is just my opinion and could be just my stereotyping, I don't think many people are foregoing using the tail and ears to help emphasize emotions to hide their emotions. There are certainly those who do but I don't think it's the general Miqo'te RPer. I think it's just something that in order to keep on with the story they only use it when it's a very intense emotion. They aren't very conscious of using them in the day to day.
Then again, I know very little.
