None of the above. But in new projects it will probably be added. It all depends if things are possible. If hair is going to be a problem, my characters will be hairless or a fake approach. I don't work with human characters or a natural looking world, so I can skip a lot of the heavy stuff if I want.

If I am going to use a feature depends on if it is doable. If something is too much to render, it will not be used or I use something else. If hair is the reason I cannot make a movie, I can give up, or loose the hair.
