I assume archive_dest is used for both archive and recovery of archives.

I think the idea is that you would turn archiving on and off regularly
while you might never change the archive_command value. Also, how would
you disable it? Set it to "", and if you do, you then have not way to
remember your command string when you want to re-enable it.
