Although as with any "common case performance improvement" this can be risky if what the common case is for a given server changes. We learned that this was what our server did when we launched in a new country and our auth server started needing 1.5x the computer per query. There was an ASCII special case and then an especially bad / expensive Unicode lookup when that failed, which we started triggering way more often.
