It would come up with a config if it doesn't remember it's other settings,
and my preference is that all devices (pretty much, but there are
exceptions) would come up in config mode.

BTW I mentioned earlier that xplhal would send a sequence of configs to a
device that couldn't remember it's assigned instance, but comes up with
pre-defined instance. Actually it cycles thru the configs by v-d.instance
and only sends the latest.

For initial (install) config you only bring one up a time (the only time
they should have the same instance is if they come up with 'default', which
then must be changed).
