I would actually push back against this from the opposite point of view - I think we should (re)claim Counseling as a part of Psychology. I understand you don't want people thinking that Masters-level LPCs are the same as Doctoral-level Clinical Psychologists, and fair enough. However, my point is that everything in Counseling comes from Psychology. The theories, the techniques, the original licensure/ethics rules, and most of the original professors all came from Psychology. I think Counseling just had to exist as a separate field because the APA would not budge on some type of Master's-level clinical practice.
Counseling being a legally separate discipline has led to scope of practice battles that have been very harmful to Psychology, and many Counseling programs no longer allowing Psychologists (or Social Workers) to teach means that our job prospects are more limited and that these Master's students are now being taught only by people with Counselor Education degrees, such as the one you mentioned who wants to replace the entire DSM with trauma. I've known great, intelligent people with CES degrees. I've also known other people with CES degrees. You can get them entirely online in about two-three years. The further Counseling drifts from Psychology the worse it gets, and the lower the average quality of teaching gets. I know, I got my Master's in Counseling!
Right now most people who say that Counseling is not a part of Psychology are partisan Counselors saying that they are a separate and equal discipline that just happens to only require a Master's degree to do all of the same things that Psychologists do. For example, in Virginia they can do any kind of Psychological testing they want, and some of their lobbying organizations advocate for them to be able to do so with only a Master's degree. Psychologists and Social Workers are also not considered qualified to supervise towards Counselor licensure here, based on the idea that we are "separate disciplines". Apparently a Psychologist could never offer the type of supervision that an LPC can. The more Counselors are their own discipline, the less influence Psychologists have, the worse their quality of teaching gets, and the more justification they have to disallow Psychologists from teaching or supervising them.
