I just have backup_label too firmly stuck in my head, but is what that

about that.
The thing it does that describes it as "recovery control" in my view is
that it contains the LSN where Postgres must start recovery (plus TLI,
backup method, etc.). There is some other informational stuff in there,
but the important fields are all about ensuring consistent recovery.
At the end of the day the entire point of backup *is* recovery and users
will interact with this file primarily in recovery scenarios.
Maybe "restore" is better than "recovery", since recovery also happens
separate from backups, but restoring is something you do with a backup
(and there is also restore_command etc.).
