Yes, you are correct, but since there are MBA/JD programs, it would be considered important enough to atleast have some discussion about the LSAT on the forum. If you apply for this joint degree they will expect both the LSAT and GMAT to consider your application.
Also, we an area for GRE b/c some MBA programs are now accepting these test scores.
Obviously though, the GMAT dominates our forums, but we would be silly to not consider our broad range of users and their needs.
