There aren't many people who want(ed) this feature, so why should it be turned on for everyone? Moreover, it only works for some AUTH methods, so it's not a complete solution. What do you mean by "a macro"? It's a compile time option, not a run time option. I don't see how a (cf/mc?) "macro" could be involved here and what the purpose/benefit would be.
