The point of this is to cover off any problems that might arise from
connection reuse.  It's clumsy.  I think that it should be reworded:
clients MUST NOT send "http" requests on a connection that would
ordinarily be used for "https" requests unless the http-opportunistic
origin object [...]

If scheme is determined on the first request and that causes this
check to pass, then we're going to get false positives.  Remember:
we're incapable of detecting all cases where the server decides to do
crazy things - I'm sure that I can devise a server architecture that
will fail for any solution we devise - we have to instead take steps
that we think are reasonable.
