I think it depends on the person and the therapy. I think this forum attaches a large amount of people (not exclusively, but a lot) for whom attachment difficulties are a part of therapy. If that's the case, then perhaps? I don't know. Different people do need different things from therapy. But I think the bigger proportion of therapy clients in general (in my experience) come with a specific issue or set of issues they wish to explore and resolve and the therapist and attachment don't come into it.
