I think you just need the right therapist for the job. Therapists have many uses. If you're going on a lovely day hike through a well-lit forest, you can probably pick any one and be fine. If you're planning to scale the Mt. Everest of attachment issues, you really need the best sherpa you can find or you're going to be in trouble quickly.

For those of us doing therapy that uses attachment/transference, it's clear that this T isn't that kind of T. If he needs to consult on something as basic as a transitional object, he's admitting that he doesn't have the appropriate training or skills to do this kind of work. It doesn't make him a poorly trained therapist; it just means he could very easily do more harm than good to somebody who is so keenly interested in working with attachment/transference. I would argue that MC probably wasn't cut out for this kind of work either, given his sloppy boundaries. It's not easy to find a therapist who can do it.
