Apparently this is now only an issue for the staging endpoint in the
immediate future, according to 
https://community.letsencrypt.org/t/acme-v2-scheduled-deprecation-of-unauthenticated-resource-gets/74380/3

On that basis, could releasing this update now wait until the next
stretch point release, or is the change to the staging endpoint still
likely to have a significant enough impact to want to make an earlier
release?
