It's rather immaterial what browsers do here. What's important is what
*existing servers* support, since that is what we're connecting with.
I tend to agree that *most* people have probably upgraded to web servers
that support TLS. But we can't guarantee it, nor can we assume that people
have upgraded to the most modern version of TLS exclusively. In fact I
think we can assume they have *not*. When the SSL issues were discovered a
couple of years back, the standard recommendation was simply to *disable*
SSLv1 and SSLv2, not to upgrade to Java 11 or some such. We still support
(and have people using!!) early forms of NTLM (v1 to be specific), for
instance. We're not going to be able to wag the dog here. Breaking
changes of this kind usually mean we go to a whole new major version of MCF.
However, if you can show that SSLContext.getSSLFactory("TLS") produces a
SSLSocketFactory that works with all versions of TLS and SSL that do not
have known security holes, I would support changing over to that. If it
turns out we need much more specificity about the kind of SSLSocketFactory
we produce, then we need a better solution anyhow for handling multiple
protocols in one socket factory.
