Well, if it's worth adding a whole new layer to my stack to deal with this kind of stuff, surely it's even more worth extending an existing layer to deal with it; as a corollary, if I know enough about the problems I'm having to know what I need Templar to do for me, then I know enough about them to know what I need nginx to do for me, too.

Again, though, maybe I'm just missing the point here. Perhaps it would help to know what use case prompted Templar's development.
