It is utterly useless and places should stop offering it.
Although I agree with you on this, it seems to me that some schools may offer some departments like this with a department name that is a little bit more academic-like, not so vocational, but "softer" than the traditional academic majors.
For example, not history, but history of sciences or medicine; not biology, but human biology or biomedical sciences (BTW, these are department names that really exist.) Some common threads among these "innovative" departments are: inter-discipline, and more importantly, the major requirements beyond the medical school pre-regs are somewhat lighter than those required by a traditional academic major (like biology or chemistry).
Ironically, these departments seem to attract more and more premeds in recent years. At some schools, if you compare the graduation requirements among several departments (i.e., those major requirements beyond the pre-reqs), they are not equal in their course load. For example, at some schools, the major/graduation requirements for a psychology major may be lighter than the traditional science majors. (BTW, many students actually believe psychology may be a "good" major for a pre-med, who is not so interested in taking sciences classes beyond the medical school pre-reqs, except one or two additional "lighter" upper-division biology classes.)
I wonder what the medical school adcom may think about this new phenomenon, that is, more and more premeds major in a somewhat "softer" academic discipline (but still in a department with a non-vocational department name.)
