I think that this mainly boils down to how much Postgres JDBC wants to
get support here as some vendors can maintain oldest versions of OpenSSL
for a long time.  The extra code is not that much complicated by the
way, still it is true that HEAD is cleaner with its simplicity.

I'm unclear what this has to do with JDBC ? JDBC doesn't use OpenSSL 

Alvaro ?

    It's only indirectly related. It does matter on what servers JDBC would be able to connect to (using SCRAM + channel binding). Only those with tls-server-end-point will be able to use CB with JDBC, and that is, as of today, only OpenSSL 1.0.2 or higher, which is not available on some older distributions.
