My gut feeling and experience is that an interaction designer should have a good understanding of the medium he's designing for, whether this is visual, physical, aural or something else. Visuals are a nice example case, though, so pardon me for concentrating on that for the rest of this reply.
One of the issues with using just the wireframes is that some problems can extend to visual domain and vice versa. A solution to an interaction problem can be a visual design issue. A visual design issue can be solved via interaction. The separation of all parts of the systems (coding, visuals, interaction, marketing, etc.) seem to be artificial, to me at least, and mostly due to practical issues. The more you can break down the barriers, the easier design seems to become. To what level that can or should be done is another complex issue. However, all this also depends on the team, how it operates and what kind of people are in it. One can't be an expert in everything, of course, yet there needs to be understanding about the various aspects. Diversity can be a solution, but there are practical limits with that as well. Plus there are benefits of keeping teams small. Thus, imho, interaction designer should be able to be at least adequate in visual design (or applicable field) to be worth his salt.
