I'm not sure about that, actually. Now that they're both in the tree,
they work nicely together and many users will think of them as one.

If they want to implement the warm standby using the (new) built-in
logic to keep retrying restore_command, they would set
standby_mode='on'. standby_mode='on' doesn't imply streaming replication.

If you want to use pg_standby or similar tools, then you would indeed
set standby_mode='off', but I think that makes sense because you're
implementing the standby functionality outside the server in that case.
