No, you missed the point of the upthread discussion: archive_mode
controls whether to start the archiver *and whether to hold onto
not-yet-archived segments*. We could maybe finesse the first point
but it's much harder to deal with the latter. The only workable
alternative I can see to keeping archive_mode is to tell people to
set archive_command to something like /usr/bin/true ... which is not
simpler, especially not on Windows.
