You can come up with all sorts of examples where complying with the ADA imposes costs that are out of proportion to any possible benefit. (e.g. handicapped accessible ramps on mountain cabins only accessible by a steep rocky trail) However, the legitimate concern is that, if you start allowing for a lot of exceptions, before you know it, organizations start finding reasons why just about everything should be an exception.

I'm not saying that I necessarily agree with the decision in this case but there are sometimes good reasons to have hard and fast rules even if they lead to arguably bad outcomes in specific cases
