That's unfortunate, in my opinion, because it was for several decades one of the most straightforward and balanced approaches to avoiding "establishment" problems without overly hindering "free exercise." The case is still important, however - not only because of the issues involved and the "test" which resulted, but for the erudite arguments and genuine efforts to remain pragmatic without sacrificing fundamental liberties on either side. The majority opinion by Chief Justice Warren Burger is one of the best on this topic in the entire history of the Court.
