Since URI hostnames are defined to be case-insensitive, we only ever see lower-case hostnames when looking up substitutions. That means that substitutions containing capital letters are inaccessible, which is a footgun that has hit many people. The handler should lower-case substitutions when they're added so that look-ups are always case-insensitive.
