by the size of the message field I believe remote admin/configuration is not included?

we could send the invalid config "error" codes/enums and tie them to pre-defined strings (using protos as source) on the client side, similar to Routing errors or simply expand the routing errors to include config errors.

clients should also be able to catch the "invalid config" within the config logic. currently the Android app waits for the Routing error to consider the config change successful or not.

Correct. The idea is that we need a general window into knowing things that only the device knows currently. This would extend to beyond config feedback mechanisms though. For instance another use that I have in mind is the event / festival case where we can push up a notification when the channel utilization spikes to unusable rates suggesting the user switch to a higher bandwidth preset.

Also duty cycle warnings is another one I had in mind.

So even more general purpose? A client would just display these in a dialog when received?

Basically, yes. Field level validation feedback may not be the level of detail we address with these messages, but we could add a reply_id to a message that precipitated a warning or error response potentially.

Seems useful
