Re: Do we still need sslVersionMax/sslVersionMin?

I think we cannot remove it. Setting the MIN version is a workaround
for *old clients* not even supporting current NSS' default min.
Setting up MAX version is a workaround for *broken clients* thinking
they can support something they announced but for some reason fail to
work with such a version. I believe most of deployments have some
really legacy software of which not a small amount behaves weirdly
enough these two options save lives; I have seen these issues several
times.
