Don't recommend that people name repos draft-author-wg-blah

... by using a bad example like the ESNI draft.

That only ends up with a need to rename the repo after adoption. And a shorter name is easier to type and remember. For instance, my preference for QUIC would have been to name it just "quic"; the ESNI draft could just as easily have been called "esni".
