I find it necessary for a lot of different types of patterns that optimize performance. See the very recently written beta react docs, they go over this quite well.

In general, I think it's always a mistake to tell people "don't use this tool because you may shoot yourself in the foot", best to explain the when and why. But I do have a problem when the tool has just stupid defaults that make it harder to use correctly in the first place.
