To teach the IPA Phonology or NOT

It's the old debate: Is teaching the IPA chart worthwhile in English Language teaching? I think everyone teaching nowadays should have a good handle on what is in the use of the IPA for a student who wants to really participate in spoken English. So many teachers don't want their students to be their peers. They simply don't believe in their students or their own abilities. In the end a teacher can keep their students "in their place" with incomplete pronunciation work. It's just not fair to tell show them everything but how to use their mouths to communicate. It's not communicative. That's my opinion, of course. Where do you stand?
