The thing about not having an option is that the choices
all offer conflicting goals.  You can choose "required" to
meet a secure-by-default goal and lose access to older
servers that don't support signing.  You can choose
"enabled" and lose the ability to definitively thwart MITM
attacks.  You can choose "disabled" and a client can't ask
for signing.  Having a switch available seems useful to me.

I think least-surprise "disabled" makes the most sense to me.
I could live with "required", since there are likely not that
many servers that can't support signing at all.

What I'd probably prefer is that a user can raise the level
of security but not lower it.  We have this with "minauth",
I believe.  I think it's reasonable to support this.
