The entire definition seems wrong to me.  Traditionally, all of the
"s" schemes mean that a secure connection must be used to access
the resource.  The notion of secure-before-access is a common pattern
that applies regardless of STARTTLS support -- it says that some
form of secure connection is required with the access.

In other words, the definition should be that snews indicates
a requirement that either RFC4642-style STARTTLS must be negotiated
with the server or that a TLS connection should be initiated first.
One way to deploy such a change is to say that if the port is
empty or 563, then initiate TLS first; otherwise, do RFC4642.

In any case, snews is not a historical scheme.  It is still
necessary to inform the client of the need for STARTTLS *before*
they start sending requests via NNTP.
