Yeah, seems reasonable.

I'd say no. In testing, I have done this many times:
pg_start_backup()
copy data directory to server
create recovery.conf
Start standby server.
pg_stop_backup()
The standby doesn't reach consistency before it sees the end-of-backup
record written by pg_stop_backup(), but it does replay up to the last
WAL segment, and connect to the master.
Not sure if that's useful in real life, but there could be situations
where restore_command isn't totally reliable, for example, and it's good
to keep trying.
