Yeah, that's a fine interface actually.
One last thought for the interface, should we return the previous
config-id?

That limits the config-id space to long (min s32) so that we can report
the negative error code (or exclude the top 4095 values).

No real use for it at the moment. I leave this up to your uAPI designer experience :)
