Well, obviously I don't entirely agree ;)

Yes, it's a convenience command. Like pg_standby was. And like many
other commands that we maintain as part of *core*, such as createuser,
vacuumdb, etc. Those can all be done with an even *simpler* command
than the one you suggest above. So I don't see that as an argument why
it wouldn't be useful.

Also, the command you suggest above does not work on Windows. You can
probably write a .BAT file to do it for you, but I'm pretty sure it's
impossible to do it as an archive_command there.
