I think you meant "a world away from 9.0".

Actually, I don't see the distance from 9.0 as a valid argument as 9.5
was probably also a world away from 9.0.

I prefer calling 9.7 as 10.0 because there will be near-zero-downtime
major upgrades with pg_logical (?), and parallelism will cover more
cases.  Built-in logical replication in 9.7 would be big too, and
another reason to do 9.7 as 10.0.

On the other hand, the _start_ of parallelism in 9.6 could be enough of
a reason to call it 10.0, with the idea that the 10-series is
increasingly parallel-aware.  You could argue that parallelism is a much
bigger deal than near-zero-downtime upgrades.

I think the fundamental issue is whether we want to lead the 10.0 branch
with parallelism, or wait for an administrative change like
near-zero-downtime major upgrades and built-in logical replication.

Someone mentioned how Postgres 8.5 became 9.0, but then someone else
said the change was made during alpha releases, not beta.  Can someone
dig up the details?
