I see another problem with allowstarttls (and its default) at least on
3.8.6. Since I'm not sure if I got it right I wanted to discuss it here
first before filing a bug.

In my/any murder world the frontends proxy all connections by connecting to
the nonTLS ports and upgrading them by using STARTTLS/UPGRADE. There is no
option to force a proxy to use implicit TLS (correct me if I'm wrong here!).

The patches for allowstarttls now practically disable proxying if a backend
forces the use of TLS (eg. for AUTH) and allowstarttls is off ...
immediately breaking a murder cluster with defaults set to false.

Disabling STARTTLS for the "outer world" only seems impossible either in
case of murder.
