I know that and you know that, but even our own manual use the exclusive 
mode in some of the examples, e.g: "pg_start_backup('label_goes_here')"[1].

Your point about that people who do not monitor their backups wont 
notice warnings is fair, but even so I think we should give people more 
time to migrate when even our own documentation isn't always clear about 
the exclusive mode being deprecated.
