It's not the replication that's read-only, it's the queries executed on
the slaves.  I haven't read the proposed docs but it sounds like this
is confusing two features that would be better explained separately,

* built-in simple replication

* ability to execute read-only queries on a replication slave server

(in this context, "simple" really means "all or nothing", as compared
to stuff like Slony that can replicate subsets of a database)
