I don't think there is any consensus. It seems to me that not many native speaking teachers use it. That's a pity in many ways, in my opinion, because it's a very useful tool. It takes the average native speaker less than an hour to be able to recognise the English phonemes , and not a great deal longer to be able to use them with a reasonable degree of confidence.
I don't think that many of those of us who use it actually teach the phonetic alphabet. We use it. Those learners who are not already familiar with it soon pick up the ability to read it, and they recognise its value. Learners don't normally have to write it from memory. They may copy it if they keep lists of new words and phraases.
